Subject: [PATCH 004/526] sunxi: usb: Drop AXP-sepcific VBUS detection and
drive logic
VBUS detection and enable is now be used with virtual AXP GPIOs, so all the USB
code has to use GPIO in every case and let sunxi_gpio do the heavy lifting.

Subject: [PATCH 006/526] sunxi: common VBUS detection logic in usbc
VBUS detection could be needed not only by the musb code (to prevent host mode),
but also by e.g. gadget drivers to start only when a cable is connected.
In addition, this allows more flexibility in vbus detection, as it could easily
be extended to other USBC indexes. Eventually, this would help making musb
support independent from a hardcoded USB controller index (0).

Subject: [PATCH 009/526] sunxi: GPIO pin mux hardware-feature-specific
function index defines
Each hardware feature exposed through the GPIO pin mux is usually using the same
function index (for a given port), so there is no need to define one value per
pin: one value per hardware feature per port is sufficient, avoids duplication
and makes everything easier to understand.

Subject: [PATCH 010/526] sunxi: Complete mmc pin mux for each supported
platform, configured with Kconfig
Sunxi platforms have different possible mmc pin mux setups (except for mmc0),
which are different across platforms.
This lets users configure which is used through the CONFIG_MMC*_PINS Kconfig
options. This is especially relevant when a second (in addition to mmc0) port
is used and CONFIG_MMC_SUNXI_SLOT_EXTRA is enabled.

Subject: [PATCH 014/526] sunxi: usbc: Initialize vusb value on
request_resources
On boards which use the pmic to enable/disable vbus on the otg port, the
vbus value is not reset to 0 on reset, as reset only resets the SoC and not
the pmic, so explicitly set vbus to 0 on init (request_resources) by moving
the gpio_direction_output call into request_resources.
For consistency also move the gpio_direction_input call for vbus-detect into
request_resources.

Subject: [PATCH 015/526] sunxi: usbc: Wait for vbus to fall after disabling it
When u-boot boots the board may be powering vbus, we turn off vbus in
sunxi_usbc_request_resources, if we are too quick with reading vusb-detect
after this we may see a residual charge and assume we've an external vusb
connected even though we do not. So when we see an external vusb wait a bit
and try again.
Without this when dealing with a pmic controller vbus and doing "reset" on
the u-boot console the musb host will only init once every other boot, because
the other boot it thinks an external vbus is present, this commit fixes this.

Subject: [PATCH 016/526] sunxi: axp221: Use vbus-available rather then
vbus-usable for vbus-detect
vbus-usable may not get set if power is provided through both the power barrel
connector and external 5v is also present on the otg connector, at least on
boards where vbus is also controlled through the axp221-pmic.
One way to reproduce this is to bootup an Ippo-q8h board with a usb-host
cable plugged into the otg (so that it will get powered), then unplug the
usb-host cable and plug in a charger, and then do "reset" on the u-boot
console, vbus-usable will then report 0, leading to uboot trying to provide
power to the otg port even though external 5v is present, this commit fixes
this.

Subject: [PATCH 029/526] i2c: mvtwsi: Support for up to 4 different
controllers
Orion5x, Kirkwood and Armada XP platforms come with a single TWSI (I2C) MVTWSI
controller. However, other platforms using MVTWSI may come with more: this is
the case on Allwinner (sunxi) platforms, where up to 4 controllers can be found
on the same chip.

Subject: [PATCH 030/526] sunxi: Complete i2c support for each supported
platform
Sunxi platforms come with at least 3 TWI (I2C) controllers and some platforms
even have up to 5. This adds support for every controller on each supported
platform, which is especially useful when using expansion ports on single-board-
computers.

Subject: [PATCH 031/526] ti: dwc3: Enable clocks in enable_basic_clocks() in
hw_data.c
Commit d3cfcb3 (ARM: DRA7: Enable clocks for USB OTGSS and USB PHY)
changed the member names of prcm_regs from cm_l3init_usb_otg_ss_clkctrl
to cm_l3init_usb_otg_ss1_clkctrl and from cm_coreaon_usb_phy_core_clkctrl
to cm_coreaon_usb_phy1_core_clkctrl in order to differentiate between
the two dwc3 controllers present in dra7xx/am43xx and enabled these
clocks in enable_basic_clocks() in hw_data.c. However these clocks
continued to be enabled in board files/driver files for dwc3 host
mode functionality causing compilation break with few configs.
Fixed it here by making all the clocks enabled in enable_basic_clocks()
and removing it from board files/driver files here.

Subject: [PATCH 032/526] x86: Support machines with >4GB of RAM
Some systems have more than 4GB of RAM. U-Boot can only place things below
4GB so any memory above that should not be used. Ignore any such memory so
that the memory size will not exceed the maximum.
This prevents gd->ram_size exceeding 4GB which causes problems for PCI
devices which use DMA.

Subject: [PATCH 033/526] x86: video: Allow keyboard presence to be controlled
by device tree
At present a VGA console assumes a keyboard unless a CONFIG option is set.
This difference can be dealt with by a device tree option, allowing boards
that are otherwise the same to use the same configuration.

Subject: [PATCH 037/526] x86: Add support for panther (Asus Chromebox)
Support running U-Boot as a coreboot payload. Tested peripherals include:
- Video (HDMI and DisplayPort)
- SATA disk
- Gigabit Ethernet
- SPI flash
USB3 does not work. This may be a problem with the USB3 PCI driver or
something in the USB3 stack and has not been investigated So far this is
disabled. The SD card slot also does not work.
For video, coreboot will need to run the OPROM to set this up.
With this board, bare support (running without coreboot) is not available
as yet.

Subject: [PATCH 038/526] sandbox: Update device tree 'reg' properties for I2C
and SPI
We should have a size value for these. Add one in each case. This will
be needed for PCI.

Subject: [PATCH 040/526] x86: Add a x86_ prefix to the x86-specific PCI
functions
These functions currently use a generic name, but they are for x86 only.
This may introduce confusion and prevents U-Boot from using these names
more widely.
In fact it should be possible to remove these at some point and use
generic functions, but for now, rename them.

Subject: [PATCH 041/526] dm: Add a new CPU init function which can use driver
model
Since driver model is set up after arch_cpu_init(), that function cannot
use drivers. Add a new arch_cpu_init_dm() function which is called
immediately after driver model is ready, and can reference devices.
This can be used to probe essential devices for the CPU.

Subject: [PATCH 044/526] fdt: Tighten up error handling in
fdtdec_get_pci_addr()
This function returns -ENOENT when the property is missing (which the caller
might forgive) and also when the property is present but incorrectly
formatted (which many callers would like to report).
Update the error return value to allow these different situations to be
distinguished.

Subject: [PATCH 045/526] dm: core: Add dev_get_uclass_priv() to access uclass
private data
Add a convenience function to access the private data that a uclass stores
for each of its devices. Convert over most existing uses for consistency
and to provide an example for others.

Subject: [PATCH 046/526] dm: core: Mark device as active before calling its
probe() method
At present the device is not active when the probe() method is called. But
some probe() methods want to set up the device and this can involve
accessing it through normal methods. For example a PCI bus may wish to
set up its PCI parameters using calls to pci_hose_write_config_dword() and
similar.
At present this does not work because every such call within the probe()
method sees that the device is not active and attempts to probe it.
Already we mark the device as probed before calling the uclass post_probe()
method. This is a subtle change but I believe the new approach is better.
Since the scope of the change is only the probe() method and all its callees
it should still be within the control of the board author.

Subject: [PATCH 047/526] dm: core: Add a uclass pre_probe() method for devices
Some uclasses want to set up a device before it is probed. Add a method
for this.
An example is with PCI, where a PCI uclass wants to set up its private
data for later use. This allows the device's uclass() method to make calls
whcih use that data (for example, read PCI memory regions from device
tree, set up bus numbers).

From ff3e077bd23c37c83d01aad105e528194e33d75e Mon Sep 17 00:00:00 2001
From: Simon Glass <sjg@chromium.org>
Date: Thu, 5 Mar 2015 12:25:25 -0700
Subject: [PATCH 050/526] dm: pci: Add a uclass for PCI
Add a uclass for PCI controllers and a generic one for PCI devices. Adjust
the 'pci' command and the existing PCI support to work with this new uclass.
Keep most of the compatibility code in a separate file so that it can be
removed one day.
TODO: Add more header file comments to the new parts of pci.h

+PCI with Driver Model
+=====================
+
+How busses are scanned
+----------------------
+
+Any config read will end up at pci_read_config(). This uses
+uclass_get_device_by_seq() to get the PCI bus for a particular bus number.
+Bus number 0 will need to be requested first, and the alias in the device
+tree file will point to the correct device:
+
+
+ aliases {
+ pci0 = &pci;
+ };
+
+ pci: pci-controller {
+ compatible = "sandbox,pci";
+ ...
+ };
+
+
+If there is no alias the devices will be numbered sequentially in the device
+tree.
+
+The call to uclass_get_device by seq() will cause the PCI bus to be probed.
+This does a scan of the bus to locate available devices. These devices are
+bound to their appropriate driver if available. If there is no driver, then
+they are bound to a generic PCI driver which does nothing.
+
+After probing a bus, the available devices will appear in the device tree
+under that bus.
+
+Note that this is all done on a lazy basis, as needed, so until something is
+touched on PCI it will not be probed.
+
+PCI devices can appear in the device tree. If they do this serves to specify
+the driver to use for the device. In this case they will be bound at
+start-up.
+
+
+Sandbox
+-------
+
+With sandbox we need a device emulator for each device on the bus since there
+is no real PCI bus. This works by looking in the device tree node for a
+driver. For example:
+
+
+ pci@1f,0 {
+ compatible = "pci-generic";
+ reg = <0xf800 0 0 0 0>;
+ emul@1f,0 {
+ compatible = "sandbox,swap-case";
+ };
+ };
+
+This means that there is a 'sandbox,swap-case' driver at that bus position.
+Note that the first cell in the 'reg' value is the bus/device/function. See
+PCI_BDF() for the encoding (it is also specified in the IEEE Std 1275-1994
+PCI bus binding document, v2.1)
+
+When this bus is scanned we will end up with something like this:
+

From: Simon Glass <sjg@chromium.org>
Date: Thu, 5 Mar 2015 12:25:26 -0700
Subject: [PATCH 051/526] dm: sandbox: pci: Add PCI support for sandbox
Add the required header information, device tree nodes and I/O accessor
functions to support PCI on sandbox. All devices are emulated by drivers
which can be added as required for testing or development.

Since sandbox does not have real devices (unless it borrows those from the
host) it must use emulations. Provide a uclass which permits PCI operations
to be passed through to an emulation device.

the capability of drawing some *str with count from lcd_drawchars is unnary.
It is always called from lcd_putc_xy with one character of and count = 1.
So we simply rename lcd_drawchars into lcd_putc_xy and remove the loops inside.

Subject: [PATCH 056/526] common/lcd_console: move single static variables into
common (static) structure
For coming implementation of lcd_console rotation, we will need some more
variables for holding information about framebuffer size, rotation, ...
For better readability we catch all them into a common structure.

Subject: [PATCH 057/526] common/lcd_console: introduce display/framebuffer
rotation
Sometimes, for example if the display is mounted in portrait mode or even if it
is mounted landscape but rotated by 180 degrees, we need to rotate our content
of the display respectively the framebuffer, so that user can read the messages
which are printed out.
For this we introduce the feature called "CONFIG_LCD_ROTATION", this may be
defined in the board-configuration if needed. After this the lcd_console will
be initialized with a given rotation from "vl_rot" out of "vidinfo_t" which is
provided by the board specific code.
If CONFIG_LCD_ROTATION is not defined, the console will be initialized with
0 degrees rotation.

Subject: [PATCH 058/526] dm: sandbox: Add a emulated PCI device as an example
This device sits on the sandbox PCI bus and provides a case-swapping
service for sandbox. It illustrates the use of both PCI I/O and PCI
memory accesses.

Subject: [PATCH 062/526] dm: x86: pci: Convert chromebook_link to use driver
model for pci
Move chromebook_link over to driver model for PCI.
This involves:
- adding a uclass for platform controller hub
- removing most of the existing PCI driver
- adjusting how CPU init works to use driver model instead
- rename the lpc compatible string (it will be removed later)
This does not really take advantage of driver model fully, but it does work.
Furture work will improve the code structure to remove many of the explicit
calls to init the board.

Subject: [PATCH 065/526] common: Make sure arch-specific map_sysmem() is
defined
In the case where the arch defines a custom map_sysmem(), make sure that
including just mapmem.h is sufficient to have these functions as they
are when the arch does not override it.
Also split the non-arch specific functions out of common.h

Subject: [PATCH 066/526] net: Provide a function to get the current MAC
address
The current implementation exposes the eth_device struct to code that
needs to access the MAC address. Add a wrapper function for this to
abstract away the pointer for this operation.

Subject: [PATCH 072/526] net: Remove the bd* parameter from net stack
functions
This value is not used by the network stack and is available in the
global data, so stop passing it around. For the one legacy function
that still expects it (init op on old Ethernet drivers) pass in the
global pointer version directly to avoid changing that interface.

Subject: [PATCH 073/526] net: Make netretry actually do something
netretry previously would only retry in one specific case (your MAC
address is not set) and no other. This is basically useless. In the DM
implementation for eth it turns this into a completely useless case
since an un-configured MAC address results in not even entering the
NetLoop. The behavior is now changed to retry any failed command
(rotating through the eth adapters if ethrotate != no).
It also defaulted to retry forever. It is now changed to default to not
retry

Subject: [PATCH 074/526] net: Access mapped physmem in net functions
Previously the net functions would access memory assuming physmem did
not need to be mapped. In sandbox, that's not the case.
Now we map the physmem specified by the user in loadaddr to the buffer
that represents that space.

Subject: [PATCH 078/526] dm: eth: Pass the packet pointer as a parameter to
recv
Stop forcing drivers to call net_process_received_packet() - formerly
called NetReceive(). Now the uclass will handle calling the driver for
each packet until the driver errors or has nothing to return. The uclass
will then pass the good packets off to the network stack by calling
net_process_received_packet().

Subject: [PATCH 087/526] sandbox: eth: Add a bridge to a real network for
sandbox
Implement a bridge between U-Boot's network stack and Linux's raw packet
API allowing the sandbox to send and receive packets using the host
machine's network interface.
This raw Ethernet API requires elevated privileges. You can either run
as root, or you can add the capability needed like so:
sudo /sbin/setcap "CAP_NET_RAW+ep" /path/to/u-boot

+Linux RAW Networking Bridge
+---------------------------
+
+The sandbox_eth_raw driver bridges traffic between the bottom of the network
+stack and the RAW sockets API in Linux. This allows much of the U-Boot network
+functionality to be tested in sandbox against real network traffic.
+
+For Ethernet network adapters, the bridge utilizes the RAW AF_PACKET API. This
+is needed to get access to the lowest level of the network stack in Linux. This
+means that all of the Ethernet frame is included. This allows the U-Boot network
+stack to be fully used. In other words, nothing about the Linux network stack is
+involved in forming the packets that end up on the wire. To receive the
+responses to packets sent from U-Boot the network interface has to be set to
+promiscuous mode so that the network card won't filter out packets not destined
+for its configured (on Linux) MAC address.
+
+The RAW sockets Ethernet API requires elevated privileges in Linux. You can
+either run as root, or you can add the capability needed like so:
+
+sudo /sbin/setcap "CAP_NET_RAW+ep" /path/to/u-boot
+
+The default device tree for sandbox includes an entry for eth0 on the sandbox
+host machine whose alias is "eth1". The following are a few examples of network
+operations being tested on the eth0 interface.
+
+sudo /path/to/u-boot -D

+DHCP

Subject: [PATCH 089/526] sandbox: eth: Add support for using the 'lo'
interface
The 'lo' interface on Linux doesn't support thinks like ARP or
link-layer access like we use to talk to a normal network interface.
A higher-level network API must be used to access localhost.
As written, this interface is limited to not supporting ICMP since the
API doesn't allow the socket to be opened for all IP traffic and be able
to receive at the same time. UDP is far more useful to test with, so it
was selected over ICMP. Ping won't work, but things like TFTP should
work.

+The 'lo' interface cannot use the RAW AF_PACKET API because the lo interface

Subject: [PATCH 090/526] net: Improve error handling
Take a pass at plumbing errors through to the users of the network stack
Currently only the start() function errors will be returned from
NetLoop(). recv() tends not to have errors, so that is likely not worth
adding. send() certainly can return errors, but this patch does not
attempt to plumb them yet. halt() is not expected to error.

Subject: [PATCH 092/526] dm: x86: spi: Convert ICH SPI driver to driver model
Convert this driver over to use driver model. Since all x86 platforms use
it, move x86 to use driver model for SPI and SPI flash. Adjust all dependent
code and remove the old x86 spi_init() function.
Note that this does not make full use of the new PCI uclass as yet. We still
scan the bus looking for the device. It should move to finding its details

Add a simple uclass for this chip which is often found in x86 systems
where the CPU is a separate device.
The device can have children, so make it scan the device tree for these.

Subject: [PATCH 095/526] x86: chromebook_link: dts: Add PCH and LPC devices
The PCH (Platform Controller Hub) is on the PCI bus, so show it as such.
The LPC (Low Pin Count) and SPI bus are inside the PCH, so put these in the
right place also.
Rename the compatible strings to be more descriptive since this board is the
only user. Once we are using driver model fully on x86, these will be
dropped.

Subject: [PATCH 105/526] cros_ec: exynos: Match up device tree with kernel
version
The U-Boot device trees are slightly different in a few places. Adjust them
to remove most of the differences. Note that U-Boot does not support the
concept of interrupts as distinct from GPIOs, so this difference remains.
For sandbox, use the same keyboard file as for ARM boards and drop the
host emulation bus which seems redundant.

Subject: [PATCH 110/526] dm: i2c: add i2c-gpio driver
This commit adds driver model support to software emulated i2c bus driver.
This driver supports kernel-style device tree bindings. Fdt properties in use:
- compatible - "i2c-gpio"
- gpios - data and clock GPIO pin phandles
- delay-us - micro seconds delay between GPIOs toggle operations,
which is 1/4 of I2C speed clock period.
Added:
- Config: CONFIG_DM_I2C_GPIO
- File: drivers/i2c/i2c-gpio.c
- File: doc/device-tree-bindings/i2c/i2c-gpio.txt
Driver base code is taken from: drivers/i2c/soft-i2c.c, changes:
- use "i2c-gpio" naming
- update comments style
- move preprocesor macros into functions
- add device tree support
- add driver model i2c support
- code cleanup,
- add Kconfig entry

Subject: [PATCH 113/526] dm: ls1021a: dts: Change address_cells and size_cells
from 2 to 1
Change address_cells and size_cells of root node and 'soc' node
from 2 to 1.
We backport ls1021a device tree source files from kernel to u-boot.
Kernel files set address_cells and size_cells to 2 in order to access
more than 4GB space.
But we don't have this requirement now and u-boot fdtdec_get_xxx interfaces
can't support property whose size is 'u64' completely.
So make this change.

entry
Once declared, you cannot access a linker_list entry since you do not have
a symbol name for it. Add llsym() macro to provide this. This avoids
searching for the symbol at run-time based on name.
An example usage is to declare a driver with U_BOOT_DRIVER(), then obtain
a pointer to that driver later.

Subject: [PATCH 124/526] dm: core: Rename driver data function to
dev_get_driver_data()
The existing get_get_of_data() function provides access to both the driver's
compatible string and its driver data. However only the latter is actually
useful. Update the interface to reflect this and fix up existing users.

Subject: [PATCH 125/526] dm: core: Mark device as active before calling uclass
probe() methods
The uclass pre-probe functions may end up calling back into the device in
some circumstances. This can fail if recursion takes place. Adjust the
ordering so that we mark the device as active early, then retract this
later if needed.

Subject: [PATCH 129/526] dm: usb: Adjust usb command to prepare for driver
model
Use 'udev' instead of 'dev' in a few places, reserving 'dev' for driver
model's struct udevice. Also adjust the code in a few minor ways to make
it easier to plumb in driver model.

Subject: [PATCH 130/526] dm: usb: Adjust usb_alloc_new_device() to return an
error
This function returns NULL on error at present. Adjust it so that we can
return a real error, as is needed with driver model. Also improve the
error handling in its caller, usb_hub_port_connect_change(), and adjust
the code order to prepare for driver model.

Subject: [PATCH 131/526] dm: usb: Convert 'usb' command to support driver
model
Adjust this command to work with the new driver model uclass. It needs to
iterate through multiple independent controllers to find hubs, and work
through their children recursively in a different way. Otherwise the
functionality is much the same.

Subject: [PATCH 134/526] dm: usb: Move descriptor setup code into its own
function
usb_new_device() is far too long and does far too much. As a first step, move
the code that does initial setup and reads a descriptor into its own function
called usb_setup_descriptor().
For XHCI the init order is different - we set up the device but don't
actually read the descriptor until after we set an address. Support this
option as a parameter to usb_setup_descriptor().
Avoid changing this torturous code more than necessary to make it easy to
review.

Subject: [PATCH 136/526] dm: usb: Complete the splitting up of
usb_new_device()
This function now calls usb_setup_device() to set up the device and
usb_hub_probe() to check if it is a hub. The XHCI special case is now a
parameter to usb_setup_device(). The latter will be used by the USB uclass
when it is added, since it does not rely on any CONFIGs or legacy data
structures.

Subject: [PATCH 145/526] dm: usb: Move storage device scanning into its own
function
The usb_stor_scan() function is quite long, so split out the code that scans
each device into its own function. Also, rather than setting up the block
device list once at the start, set it up as each device is scanned. This
makes it possible to use this code from driver model.

Subject: [PATCH 149/526] dm: usb: Allow ECHI to hold private data for the
controller
Add a private data pointer that clients of EHCI can use to access their
private information. This establishes a link between struct ehci_ctrl and
its associated controller data structure.

Subject: [PATCH 150/526] dm: usb: tegra: Store the controller type explicitly
At present the tegra driver uses a separate pointer to know which controller
type is in use. This works because only one controller type is used at a
time.
With driver model we want to make the controller state hermetic in the sense
that it is not necessary to look elsewhere to know the controller type. This
will permit a controller to implement the EHCI weak functions without
reference to global data structures.
To achieve this, define an enum for the controller type and store it with
the information on each EHCI controller.

Subject: [PATCH 155/526] dm: usb: ehci: Use a function to find the controller
from struct udevice
With driver model we want to remove the controller pointer in struct udevice
and use driver model data structures instead. To prepare for this, move
access to this field to a function which can provide a different
implementation for driver model.

Subject: [PATCH 156/526] dm: usb: Refactor EHCI init
Move the bulk of the code in usb_lowlevel_init() into a separate function
which will also be used by driver model. Keep the CONFIG options out of
this function by providing a tweak flag for Faraday. We need to avoid using
CONFIG options in driver model code where possible, since it makes it
impossible to use multiple controllers in that code where they have
different options.
The CONFIG_EHCI_HCD_INIT_AFTER_RESET option is also kept out of the
common init function. With driver model the controller will be able to
perform this extra init itself after registering with the EHCI layer.

consistent function signatures, we can in good conscience move them to
a struct.

Subject: [PATCH 160/526] dm: usb: Allow USB drivers to be declared and
auto-probed
USB devices in U-Boot are currently probed only after all devices have
been enumerated. Each type of device is probed by custom code, e.g.:
- USB storage
- Keyboard
- Ethernet
With driver model this approach doesn't work very well. We could build
a picture of the bus and then go back and add the devices later, but
this means that the data structures are incomplete for quite a while.
It also does not follow the model of being able to bind a device when we
discover it.
We would prefer to have devices automatically be bound as the device is
enumerated. This allows us to attach drivers to particular USB classes
or product/vendor IDs. This is the method used by Linux.
Add the required #defines from Linux, a way of declaring a USB driver and
the logic to locate the correct driver given the USB device's descriptors.

Subject: [PATCH 161/526] dm: usb: Bind generic USB devices when there is no
driver
At present USB devices with no driver model driver cannot be seen in the
device list, and we fail to set them up correctly. This means they cannot
be used.
While having real drivers that support driver model for all USB devices
is the eventual goal, we are not there yet.
As a stop-gap, add a generic USB driver which is bound when we do not have
a real driver. This allows the device to be set up and shown on the bus.
It also allows ad-hoc code (such as usb_ether) to find these devices and
set them up.

Subject: [PATCH 162/526] dm: usb: Allow setting up a USB controller as a
device/gadget
Some controllers support OTG (on-the-go) where they can operate as either
host or device. The gadget layer in U-Boot supports this.
While this layer does not interact with driver model, we can provide a
function which sets up the controller in the correct way. This way the code
at least builds (although it likely will not work).

Subject: [PATCH 167/526] dm: usb: sandbox: Add a uclass for USB device
emulation
With sandbox we want to be able to emulate USB devices so that we can test
the USB stack. Add a uclass to support this. It implements the same
operations as a normal USB device driver, but in this case passes them on
to an emulation driver.

+How USB works with driver model
+===============================
+
+Introduction
+------------
+
+Driver model USB support makes use of existing features but changes how
+drivers are found. This document provides some information intended to help
+understand how things work with USB in U-Boot when driver model is enabled.
+
+
+Enabling driver model for USB
+-----------------------------
+
+A new CONFIG_DM_USB option is provided to enable driver model for USB. This
+causes the USB uclass to be included, and drops the equivalent code in
+usb.c. In particular the usb_init() function is then implemented by the
+uclass.
+
+
+Support for EHCI and XHCI
+-------------------------
+
+So far OHCI is not supported. Both EHCI and XHCI drivers should be declared
+as drivers in the USB uclass. For example:
+
+static const struct udevice_id ehci_usb_ids[] = {
+ { .compatible = "nvidia,tegra20-ehci", .data = USB_CTLR_T20 },
+ { .compatible = "nvidia,tegra30-ehci", .data = USB_CTLR_T30 },
+ { .compatible = "nvidia,tegra114-ehci", .data = USB_CTLR_T114 },
+ { }
+};
+
+U_BOOT_DRIVER(usb_ehci) = {
+ .name = "ehci_tegra",
+ .id = UCLASS_USB,
+ .of_match = ehci_usb_ids,
+ .ofdata_to_platdata = ehci_usb_ofdata_to_platdata,
+ .probe = tegra_ehci_usb_probe,
+ .remove = tegra_ehci_usb_remove,
+ .ops = &ehci_usb_ops,
+ .platdata_auto_alloc_size = sizeof(struct usb_platdata),
+ .priv_auto_alloc_size = sizeof(struct fdt_usb),
+ .flags = DM_FLAG_ALLOC_PRIV_DMA,
+};
+
+Here ehci_usb_ids is used to list the controllers that the driver supports.
+Each has its own data value. Controllers must be in the UCLASS_USB uclass.
+
+The ofdata_to_platdata() method allows the controller driver to grab any
+necessary settings from the device tree.
+
+The ops here are ehci_usb_ops. All EHCI drivers will use these same ops in
+most cases, since they are all EHCI-compatible. For EHCI there are also some
+special operations that can be overridden when calling ehci_register().
+
+The driver can use priv_auto_alloc_size to set the size of its private data.
+This can hold run-time information needed by the driver for operation. It
+exists when the device is probed (not when it is bound) and is removed when
+the driver is removed.
+
+Note that usb_platdata is currently only used to deal with setting up a bus
+in USB device mode (OTG operation). It can be omitted if that is not
+supported.
+
+The driver's probe() method should do the basic controller init and then
+call ehci_register() to register itself as an EHCI device. It should call
+ehci_deregister() in the remove() method. Registering a new EHCI device
+does not by itself cause the bus to be scanned.
+
+The old ehci_hcd_init() function is no-longer used. Nor is it necessary to
+set up the USB controllers from board init code. When 'usb start' is used,
+each controller will be probed and its bus scanned.
+
+XHCI works in a similar way.
+
+
+Data structures
+---------------
+
+The following primary data structures are in use:
+
+- struct usb_device
+ This holds information about a device on the bus. All devices have
+ this structure, even the root hub. The controller itself does not
+ have this structure. You can access it for a device 'dev' with
+ dev_get_parentdata(dev). It matches the old structure except that the
+ parent and child information is not present (since driver model
+ handles that). Once the device is set up, you can find the device
+ descriptor and current configuration descriptor in this structure.
+
+- struct usb_platdata
+ This holds platform data for a controller. So far this is only used
+ as a work-around for controllers which can act as USB devices in OTG
+ mode, since the gadget framework does not use driver model.
+
+- struct usb_dev_platdata
+ This holds platform data for a device. You can access it for a
+ device 'dev' with dev_get_parent_platdata(dev). It holds the device
+ address and speed - anything that can be determined before the device
+ driver is actually set up. When probing the bus this structure is
+ used to provide essential information to the device driver.
+
+- struct usb_bus_priv
+ This is private information for each controller, maintained by the
+ controller uclass. It is mostly used to keep track of the next
+ device address to use.
+
+Of these, only struct usb_device was used prior to driver model.
+
+
+USB buses
+---------
+
+Given a controller, you know the bus - it is the one attached to the
+controller. Each controller handles exactly one bus. Every controller has a
+root hub attached to it. This hub, which is itself a USB device, can provide
+one or more 'ports' to which additional devices can be attached. It is
+possible to power up a hub and find out which of its ports have devices
+attached.
+
+Devices are given addresses starting at 1. The root hub is always address 1,
+and from there the devices are numbered in sequence. The USB uclass takes
+care of this numbering automatically during enumeration.
+
+USB devices are enumerated by finding a device on a particular hub, and
+setting its address to the next available address. The USB bus stretches out
+in a tree structure, potentially with multiple hubs each with several ports
+and perhaps other hubs. Some hubs will have their own power since otherwise
+the 5V 500mA power supplied by the controller will not be sufficient to run
+very many devices.
+
+Enumeration in U-Boot takes a long time since devices are probed one at a
+time, and each is given sufficient time to wake up and announce itself. The
+timeouts are set for the slowest device.
+
+Up to 127 devices can be on each bus. USB has four bus speeds: low
+(1.5Mbps), full (12Mbps), high (480Mbps) which is only available with USB2
+and newer (EHCI), and super (5Gbps) which is only available with USB3 and
+newer (XHCI). If you connect a super-speed device to a high-speed hub, you
+will only get high-speed.
+
+
+USB operations
+--------------
+
+As before driver model, messages can be sent using submit_bulk_msg() and the
+like. These are now implemented by the USB uclass and route through the
+controller drivers. Note that messages are not sent to the driver of the
+device itself - i.e. they don't pass down the stack to the controller.
+U-Boot simply finds the controller to which the device is attached, and sends
+the message there with an appropriate 'pipe' value so it can be addressed
+properly. Having said that, the USB device which should receive the message
+is passed in to the driver methods, for use by sandbox. This design decision
+is open for review and the code impact of changing it is small since the
+methods are typically implemented by the EHCI and XHCI stacks.
+
+Controller drivers (in UCLASS_USB) themselves provide methods for sending
+each message type. For XHCI an additional alloc_device() method is provided
+since XHCI needs to allocate a device context before it can even read the
+device's descriptor.
+
+These methods use a 'pipe' which is a collection of bit fields used to
+describe the type of message, direction of transfer and the intended
+recipient (device number).
+
+
+USB Devices
+-----------
+
+USB devices are found using a simple algorithm which works through the
+available hubs in a depth-first search. Devices can be in any uclass, but
+are attached to a parent hub (or controller in the case of the root hub) and
+so have parent data attached to them (this is struct usb_device).
+
+By the time the device's probe() method is called, it is enumerated and is
+ready to talk to the host.
+
+The enumeration process needs to work out which driver to attach to each USB
+device. It does this by examining the device class, interface class, vendor
+ID, product ID, etc. See struct usb_driver_entry for how drivers are matched
+with USB devices - you can use the USB_DEVICE() macro to declare a USB
+driver. For example, usb_storage.c defines a USB_DEVICE() to handle storage
+devices, and it will be used for all USB devices which match.
+
+
+
+Technical details on enumeration flow
+-------------------------------------
+
+It is useful to understand precisely how a USB bus is enumerating to avoid
+confusion when dealing with USB devices.
+
+Device initialisation happens roughly like this:
+
+- At some point the 'usb start' command is run
+- This calls usb_init() which works through each controller in turn
+- The controller is probed(). This does no enumeration.
+- Then usb_scan_bus() is called. This calls usb_scan_device() to scan the
+(only) device that is attached to the controller - a root hub
+- usb_scan_device() sets up a fake struct usb_device and calls
+usb_setup_device(), passing the port number to be scanned, in this case port
+0
+- usb_setup_device() first calls usb_prepare_device() to set the device
+address, then usb_select_config() to select the first configuration
+- at this point the device is enumerated but we do not have a real struct
+udevice for it. But we do have the descriptor in struct usb_device so we can
+use this to figure out what driver to use
+- back in usb_scan_device(), we call usb_find_child() to try to find an
+existing device which matches the one we just found on the bus. This can
+happen if the device is mentioned in the device tree, or if we previously
+scanned the bus and so the device was created before
+- if usb_find_child() does not find an existing device, we call
+usb_find_and_bind_driver() which tries to bind one
+- usb_find_and_bind_driver() searches all available USB drivers (declared
+with USB_DEVICE()). If it finds a match it binds that driver to create a new
+device.
+- If it does not, it binds a generic driver. A generic driver is good enough
+to allow access to the device (sending it packets, etc.) but all
+functionality will need to be implemented outside the driver model.
+- in any case, when usb_find_child() and/or usb_find_and_bind_driver() are
+done, we have a device with the correct uclass. At this point we want to
+probe the device
+- first we store basic information about the new device (address, port,
+speed) in its parent platform data. We cannot store it its private data
+since that will not exist until the device is probed.
+- then we call device_probe() which probes the device
+- the first probe step is actually the USB controller's (or USB hubs's)
+child_pre_probe() method. This gets called before anything else and is
+intended to set up a child device ready to be used with its parent bus. For
+USB this calls usb_child_pre_probe() which grabs the information that was
+stored in the parent platform data and stores it in the parent private data
+(which is struct usb_device, a real one this time). It then calls
+usb_select_config() again to make sure that everything about the device is
+set up
+- note that we have called usb_select_config() twice. This is inefficient
+but the alternative is to store additional information in the platform data.
+The time taken is minimal and this way is simpler
+- at this point the device is set up and ready for use so far as the USB
+subsystem is concerned
+- the device's probe() method is then called. It can send messages and do
+whatever else it wants to make the device work.
+
+Note that the first device is always a root hub, and this must be scanned to
+find any devices. The above steps will have created a hub (UCLASS_USB_HUB),
+given it address 1 and set the configuration.
+
+For hubs, the hub uclass has a post_probe() method. This means that after
+any hub is probed, the uclass gets to do some processing. In this case
+usb_hub_post_probe() is called, and the following steps take place:
+
+- usb_hub_post_probe() calls usb_hub_scan() to scan the hub, which in turn
+calls usb_hub_configure()
+- hub power is enabled
+- we loop through each port on the hub, performing the same steps for each
+- first, check if there is a device present. This happens in
+usb_hub_port_connect_change(). If so, then usb_scan_device() is called to
+scan the device, passing the appropriate port number.
+- you will recognise usb_scan_device() from the steps above. It sets up the
+device ready for use. If it is a hub, it will scan that hub before it
+continues here (recursively, depth-first)
+- once all hub ports are scanned in this way, the hub is ready for use and
+all of its downstream devices also
+- additional controllers are scanned in the same way
+
+The above method has some nice properties:
+
+- the bus enumeration happens by virtue of driver model's natural device flow
+- most logic is in the USB controller and hub uclasses; the actual device
+drivers do not need to know they are on a USB bus, at least so far as
+enumeration goes
+- hub scanning happens automatically after a hub is probed
+
+
+Hubs
+----
+
+USB hubs are scanned as in the section above. While hubs have their own
+uclass, they share some common elements with controllers:
+
+- they both attach private data to their children (struct usb_device,
+accessible for a child with dev_get_parentdata(child))
+- they both use usb_child_pre_probe() to set up their children as proper USB
+devices
+
+
+Example - Mass Storage
+----------------------
+
+As an example of a USB device driver, see usb_storage.c. It uses its own
+uclass and declares itself as follows:
+
+U_BOOT_DRIVER(usb_mass_storage) = {
+ .name = "usb_mass_storage",
+ .id = UCLASS_MASS_STORAGE,
+ .of_match = usb_mass_storage_ids,
+ .probe = usb_mass_storage_probe,
+};
+
+static const struct usb_device_id mass_storage_id_table[] = {
+ { .match_flags = USB_DEVICE_ID_MATCH_INT_CLASS,
+ .bInterfaceClass = USB_CLASS_MASS_STORAGE},
+ { } /* Terminating entry */
+};
+
+USB_DEVICE(usb_mass_storage, mass_storage_id_table);
+
+The USB_DEVICE() macro attaches the given table of matching information to
+the given driver. Note that the driver is declared in U_BOOT_DRIVER() as
+'usb_mass_storage' and this must match the first parameter of USB_DEVICE.
+
+When usb_find_and_bind_driver() is called on a USB device with the
+bInterfaceClass value of USB_CLASS_MASS_STORAGE, it will automatically find
+this driver and use it.
+
+
+Counter-example: USB Ethernet
+-----------------------------
+
+As an example of the old way of doing things, see usb_ether.c. When the bus
+is scanned, all Ethernet devices will be created as generic USB devices (in
+uclass UCLASS_USB_DEV_GENERIC). Then, when the scan is completed,
+usb_host_eth_scan() will be called. This looks through all the devices on
+each bus and manually figures out which are Ethernet devices in the ways of
+yore.
+
+In fact, usb_ether should be moved to driver model. Each USB Ethernet driver
+(e.g drivers/usb/eth/asix.c) should include a USB_DEVICE() declaration, so
+that it will be found as part of normal USB enumeration. Then, instead of a
+generic USB driver, a real (driver-model-aware) driver will be used. Since
+Ethernet now supports driver model, this should be fairly easy to achieve,
+and then usb_ether.c and the usb_host_eth_scan() will melt away.
+
+
+Sandbox
+-------
+
+All driver model uclasses must have tests and USB is no exception. To
+achieve this, a sandbox USB controller is provided. This can make use of
+emulation drivers which pretend to be USB devices. Emulations are provided
+for a hub and a flash stick. These are enough to create a pretend USB bus
+(defined by the sandbox device tree sandbox.dts) which can be scanned and
+used.
+
+Tests in test/dm/usb.c make use of this feature. It allows much of the USB
+stack to be tested without real hardware being needed.
+
+Here is an example device tree fragment:
+
+ usb@1 {
+ compatible = "sandbox,usb";
+ hub {
+ compatible = "usb-hub";
+ usb,device-class = <USB_CLASS_HUB>;
+ hub-emul {
+ compatible = "sandbox,usb-hub";
+ #address-cells = <1>;
+ #size-cells = <0>;
+ flash-stick {
+ reg = <0>;
+ compatible = "sandbox,usb-flash";
+ sandbox,filepath = "flash.bin";
+ };
+ };
+ };
+ };
+
+This defines a single controller, containing a root hub (which is required).
+The hub is emulated by a hub emulator, and the emulated hub has a single
+flash stick to emulate on one of its ports.
+
+When 'usb start' is used, the following 'dm tree' output will be available:
+
+ usb [ + ] `-- usb@1
+ usb_hub [ + ] `-- hub
+ usb_emul [ + ] |-- hub-emul
+ usb_emul [ + ] | `-- flash-stick
+ usb_mass_st [ + ] `-- usb_mass_storage
+
+
+This may look confusing. Most of it mirrors the device tree, but the
+'usb_mass_storage' device is not in the device tree. This is created by
+usb_find_and_bind_driver() based on the USB_DRIVER in usb_storage.c. While
+'flash-stick' is the emulation device, 'usb_mass_storage' is the real U-Boot
+USB device driver that talks to it.
+
+
+Future work
+-----------
+
+It is pretty uncommon to have a large USB bus with lots of hubs on an
+embedded system. In fact anything other than a root hub is uncommon. Still
+it would be possible to speed up enumeration in two ways:
+
+- breadth-first search would allow devices to be reset and probed in
+parallel to some extent
+- enumeration could be lazy, in the sense that we could enumerate just the
+root hub at first, then only progress to the next 'level' when a device is
+used that we cannot find. This could be made easier if the devices were
+statically declared in the device tree (which is acceptable for production
+boards where the same, known, things are on each bus).
+
+But in common cases the current algorithm is sufficient.
+
+Other things that need doing:
+- Convert usb_ether to use driver model as described above
+- Test that keyboards work (and convert to driver model)
+- Move the USB gadget framework to driver model
+- Implement OHCI in driver model
+- Implement USB PHYs in driver model
+- Work out a clever way to provide lazy init for USB devices

Subject: [PATCH 196/526] dm: spi_flash: fix wrong dependency
CONFIG_SPI does not exist in Kconfig in the first place, so the
dependency "depends on DM && SPI" is never met, i.e., DM_SPI_FLASH
can never be enabled (unless you ignore the dependency in an illegal
way. See below.)
Actually, some defconfigs such as socfpga_*_defconfig define
CONFIG_DM_SPI_FLASH=y, but it never appears in the .config file
because of this wrong dependency.
On the other hand, all the Tegra boards enable DM_SPI_FLASH because
config DM_SPI_FLASH
default y
silently ignores the dependency.
Unfortunately, this style of CONFIG definition is abused everywhere
in U-Boot, so we easily miss such a wrong dependency.

Subject: [PATCH 197/526] dm: select CONFIG_DM* options
As mentioned in the previous commit, adding default values in each
Kconfig causes problems because it does not co-exist with the
"depends on" syntax. (Please note this is not a bug of Kconfig.)
We should not do so unless we have a special reason. Actually,
for CONFIG_DM*, we have no good reason to do so.
Generally, CONFIG_DM is not a user-configurable option. Once we
convert a driver into Driver Model, the board only works with Driver
Model, i.e. CONFIG_DM must be always enabled for that board.
So, using "select DM" is more suitable rather than allowing users to
modify it. Another good thing is, Kconfig warns unmet dependencies
for "select" syntax, so we easily notice bugs.
Actually, CONFIG_DM and other related options have been added
without consistency: some into arch/*/Kconfig, some into
board/*/Kconfig, and some into configs/*_defconfig.
This commit prefers "select" and cleans up the following issues.
[1] Never use "CONFIG_DM=n" in defconfig files
It is really rare to add "CONFIG_FOO=n" to disable CONFIG options.
It is more common to use "# CONFIG_FOO is not set". But here, we
do not even have to do it.
Less than half of OMAP3 boards have been converted to Driver Model.
Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is
weird. Instead, add "select DM" only to appropriate boards, which
eventually eliminates "CONFIG_DM=n", etc.
[2] Delete redundant CONFIGs
Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again
in configs/sandbox_defconfig.
Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and
defines it also in omap3_beagle_defconfig and devkit8000_defconfig.

Subject: [PATCH 208/526] net: cosmetic: Change IPaddr_t to struct in_addr
This patch is simply clean-up to make the IPv4 type that is used match
what Linux uses. It also attempts to move all variables that are IP
addresses use good naming instead of CamelCase. No functional change.

Date: Wed, 8 Apr 2015 01:41:02 -0500
Subject: [PATCH 209/526] net: cosmetic: Fixup var names related to boot file
The variables around the bootfile were inconsistent and used CamelCase.
Update them to make the code more readable.

From 1fd92db83d399ff7918e51ba84bc73d2466b5eb6 Mon Sep 17 00:00:00 2001
From: Joe Hershberger <joe.hershberger@ni.com>
Date: Wed, 8 Apr 2015 01:41:06 -0500
Subject: [PATCH 213/526] net: cosmetic: Fix var naming net <-> eth drivers
Update the naming convention used in the network stack functions and
variables that Ethernet drivers use to interact with it.
This cleans up the temporary hacks that were added to this interface
along with the DM support.
This patch has a few remaining checkpatch.pl failures that would be out
of the scope of this patch to fix (drivers that are in gross violation
of checkpatch.pl).
Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
Acked-by: Simon Glass <sjg@chromium.org>

Subject: [PATCH 229/526] net: Fix incorrect DHCP/BOOTP packets on 64-bit
systems
This commit fixes incorrect DHCP/BOOTP packet layout caused by
'ulong' type size difference on 64 and 32-bit architectures.
It also renames NetReadLong()/NetCopyLong() to
net_read_u32/net_copy_u32() accordingly.

Subject: [PATCH 231/526] net: Fix compile errors when SNTP enabled and not
DATE
When SNTP is enabled and DATE is not, to_tm() is not built in. It could
be defined when TIMESTAMP is defined, so check for that.

+Child nodes of the Ethernet controller are typically the individual PHY devices

Subject: [PATCH 236/526] dm: net: Use existing Ethernet init for driver model
At present even with driver model is used there is still much manual init
of related devices: PHY, environment and board init. Until these requirements
are dealt with in another way we need to keep them around.
Break out the init portion of the legacy eth_initialize() into a separate
function and call it from both the legacy and driver model eth_initialize()
functions.

Subject: [PATCH 238/526] dm: net: Adjust PHY interface to work with
CONFIG_DM_ETH
When driver model is used for Ethernet a few functions are passed a udevice
instead of an eth_device. Also add a function to find a PHY type given its
name. This will be used to decode the device tree node.
Finally, put a phy_interface field in struct eth_pdata since this is an
important part of the platform data for Ethernet.

Subject: [PATCH 239/526] dm: net: Tidy up designware driver ready for driver
model
Adjust the error handling to use errno.h instead of returning -1. Change
leaf functions to pass in the arguments they require rather than struct
eth_device. Apart from simplifying the code it makes is easier to reuse
these functions for driver model, since mostly they actually only use
struct dw_eth_priv (which we can keep).
Create a stub for each Ethernet operation function. This will allow use to
share code with the driver model versions.

Adjust the Ethernet initialisation code to support driver model.
It is no-longer necessary to call designware_initialize(). The device will
be probed when it is used. The PHY type and GMAC base will come from the

Subject: [PATCH 257/526] ahci: mmio_base is a virtual address
Don't store it in a u32.
Don't dereference the bus address as if it were a virtual address
(fixes 284231e49a2b4 ("ahci: Support splitting of read transactions
into multiple chunks")).
Fixes crash on boot in MPC8641HPCN_36BIT target.

Subject: [PATCH 260/526] buildman: Adjust the 'aborted' heuristic for writing
output
At present buildman tries to detect an aborted build and doesn't record a
result in that case. This is to make sure that an abort (e.g. with Ctrl-C)
does not mark the build as done. Without this option, buildman would never
retry the build unless -f/-F are provided. The effect is that aborting the
build creates 'fake errors' on whatever builds buildman happens to be
working on at the time.
Unfortunately the current test is not reliable and this detection can
trigger if a required toolchain tool is missing. In this case the toolchain
problem is never reported.
Adjust the logic to continue processing the build result, mark the build as
done (and failed), but with a return code which indicates that it should be
retried.
The correct fix is to fully and correctly detect an aborted build, quit
buildman immediately and not write any partial build results in this case.
Unfortunately this is currently beyond my powers and is left as an exercise
for the reader (and patches are welcome).

Subject: [PATCH 262/526] buildman: Allow comparison of build configuration
It is useful to be able to see CONFIG changes made by commits. Add this
feature to buildman using the -K flag so that all CONFIG changes are
reported.
The CONFIG options exist in a number of files. Each is reported
individually as well as a summary that covers all files. The output
shows three parts: green for additions, red for removals and yellow for
changes.

Subject: [PATCH 263/526] buildman: Keep more outputs with the --keep-outputs
flag
When told to keep outputs, be much more liberal in what files we keep.
In addition to adding 'MLO', keep anything that matches u-boot-spl.* (so
that we keep the map file as well) and anything we generate about
'u-boot itself. A large number of bootable formats now match this and
thus it's easier to build many targets and then boot them afterwards
using buildman.

Subject: [PATCH 270/526] sandbox: Implement host dev [device]
A common pattern to check if a certain device exists (e.g. in
config_distro_bootcmd) is to use: <interface> dev [device]
Implement host dev [device] so this pattern can be used for sandbox host
devices.

Subject: [PATCH 274/526] sandbox: add config_distro_defaults and
config_distro_bootcmd
Make the sandbox setup more generic/examplary by including
config_distro_defaults.h and config_distro_bootcmd.h.
Among other things this makes it easy to test whether images will boot
though with the standard distro bootcmds by running e.g:
u-boot -c 'host bind 0 myimage.img ; boot'
By default there are 2 target host devices to emulate device with
multiple storage devices (e.g. internal ("host 0") and external
("host 1") and verify that the prioritization and fallbacks do work
correctly.

Subject: [PATCH 278/526] MPC8541/MPC8555: Enable SS_EN in DDR_SDRAM_CLK_CNLT
register
According to the MPC8555/MPC8541 reference manual the SS_EN (source
synchronous enable) bit in the DDR_SDRAM_CLK_CNLT register must be set
during initialization.
>From section 9.4.1.8 of that manual:
Source synchronous enable. This bit field must be set during
initialization. See Section 9.6.1, "DDR SDRAM Initialization
Sequence," details.
0 - Reserved
1 - The address and command are sent to the DDR SDRAMs source
synchronously.
In addition, Freescale application note AN2805 is also very clear that
this bit must be set.
This patch reverts a change introduced by commit
457caecdbca3df21a93abff19eab12dbc61b7897.
Testing Done:
Compiled targets CONFIG_TARGET_MPC8555CDS and CONFIG_TARGET_MPC8541CDS
and inspected the generated assembly code to verify the SS_EN bit was being
set. There is one extra instruction emitted:
fff9b774: 65 29 80 00 oris r9,r9,32768
Compiled the CONFIG_TARGET_MPC8548CDS target and verified that no
additional instructions were emitted related to this patch.
Booted an image on a MPC8541 based board successfully.

Subject: [PATCH 279/526] qemu-ppce500: Add support for 64bit CCSR map
QEMU 2.3 changes the address layout of the CCSR map in the PV ppce500 machine
to reside in higher address space.
Unfortunately, this exposed a glitch in u-boot for ppce500: While providing
a function to dynamically evaluate the CCSR region's position in physical
address space, we never used it. Plus we forgot to support 64bit physical
addresses.
This patch fixes that mishap, making u-boot work fine with latest QEMU again.

Subject: [PATCH 281/526] board/t208xrdb: VID support
The fuse status register provides the values from on-chip
voltage ID efuses programmed at the factory.
These values define the voltage requirements for
the chip. u-boot reads FUSESR and translates the values
into the appropriate commands to set the voltage output
value of an external voltage regulator.

Subject: [PATCH 284/526] powerpc/mpc85xx: Don't relocate exception vectors
Booke does not require exception vectors to be located at address zero.
U-Boot was doing so anyway, simply because that's how it had been done
on other PPC. The downside of this is that once the OS is loaded to
address zero, the exception vectors have been overwritten -- which
makes it difficult to diagnose a crash that happens after that point.
The IVOR setup and trap entry code is simplified somewhat as a result.
Also, there is no longer a need to align individual exceptions on 0x100
byte boundaries.

Subject: [PATCH 285/526] powerpc/mpc85xx: Remove some dead code
U-Boot does not have system calls (the services it exposes to
standalone commands use a different mechanism), so the syscall handler
is dead code. It's also broken code, as it assumes it is located at
0xc00 -- while even before the patch to stop relocating exception
vectors to 0, U-Boot had the syscall at 0x900.
The critical and machine check return paths are never called -- the
regular exception return path is used instead, which works because
xSRR0/1 have already been saved and can be restored via the regular
SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck
inside another exception prolog/epilog).
Also remove a few other small unused functions.

Subject: [PATCH 287/526] powerpc/mpc8641hpcn: Move environment to avoid
conflict
U-Boot on this board grew a long time ago past the 384 KiB that
it reserves for the U-Boot image, before the environment. Thus,
saveenv overwrites the U-Boot image and bricks the board.
I tried to find out when U-Boot grew beyond this point, but there is a
long stretch in the history where this board did not build -- and
AFAICT when it did fit in 384 KiB, it was missing vital features such
as fdt support. Turning off CONFIG_VIDEO was not enough to make it
fit. Thus, I don't think we have any choice other than to move the
environment.

Subject: [PATCH 288/526] net: phy: realtek: Disable interrupt on Realtek
Ethernet PHY drivers
Some Realtek Ethernet PHYs, like RTL8211D(G/N) and RTL8211E(G), have
interrupts enabled by default. If the interrupt is not treated later by
the OS and the PHY's interrupt line is enabled and shared with other
interrupts, the system will get an interrupt storm. This patch disables
the interrupt for PHY devices that use one of the current Realtek
Ethernet PHY drivers. Some of Realtek Ethernet PHYs, such as RTL8211B(L)
have the interrupt masked. In this case, the functionality of the PHY
should not be afected since this patch brings INER and INSR registers to
their default values.

Turn ioaddr into an unsigned long rather than a sized 32-bit variable.
While at it, fix a couple of pointer to integer cast size mismatch
warnings by casting through unsigned long going from pointers to
integers and vice versa.

Subject: [PATCH 291/526] mii: add read-modify-write option to mii command
When accessing PHY registers it is often desirable to only update
selected bits, so it is necessary to first read the current value
before writing back an modified value with the relevant bits
updated.
To simplify this and to allow such operations to be incorporated
into simple shell scripts propose adding a 'modify' option to the
existing mii command, which takes a mask indicating the bits to
be updated in addition to a data value containing the new bits,
ie, <updated> = (<data> & <mask>) | (<current> & ~<mask>).

Subject: [PATCH 308/526] arm: socfpga: spl: Add s_init stub
Add a stub s_init function in the board file. The reason why the stub function
is needed is that most of the work is now being done in board_init_f(), there
is no need for the SPL to do anything s_init(). However, since lowlevel_init()
is still branching to s_init(), we need stub function for now, until
lowlevel_init() morphs into s_init().

commit aed2fbef5e9a0ab5a7cd01e742039a962f0b24ef
"dm: serial: Tidy up the pl01x driver"
caused a regression on (real hardware) PL010 by omitting
to update the line control register when switching baudrate.
Fix this by inlining the missing write to the baud control
register.
Also renaming the set_line_control() function to
pl011_set_line_control() since this function is clearly
PL011-specific, and it won't suffice to call that to
set up line control.
Tested on the Integrator/AP hardware.

Subject: [PATCH 319/526] Add bootscript support to esbc_validate.
1. Default environment will be used for secure boot flow
which can't be edited or saved.
2. Command for secure boot is predefined in the default
environment which will run on autoboot (and autoboot is
the only option allowed in case of secure boot) and it
looks like this:
#define CONFIG_SECBOOT \
"setenv bs_hdraddr 0xe8e00000;" \
"esbc_validate $bs_hdraddr;" \
"source $img_addr;" \
"esbc_halt;"
#endif
3. Boot Script can contain esbc_validate commands and bootm command.
Uboot source command used in default secure boot command will
run the bootscript.
4. Command esbc_halt added to ensure either bootm executes
after validation of images or core should just spin.

ft_pcie_setup, then removes unnecessary pcie_layerscape.h because
all the functions have been declared in common.h.

Subject: [PATCH 323/526] pci/layerscape: fix link and class issues to support
ls2085a
1. LS2085a provides PCIE_LUT_DBG register rather than PCIE_LDBG
to show the link status, so the patch fixes it.
2. Increase the delay time to make sure that link training
has finished.
3. Return invalid value when accessing multi-function device
4. For LS2085a DBI_RO_WR_EN bit is cleared as default, so we
must set this bit before change DBI register value.

Subject: [PATCH 327/526] armv8/fsl-lsch3: Add Freescale Debug Server driver
The Debug Server driver is responsible for loading the Debug
server FW on the Service Processor (Cortex-A5 core) on LS2085A like
SoCs and then polling for the successful initialization of the same.
TOP MEM HIDE is adjusted to ensure the space required by Debug Server
FW is accounted for. MC uses the DDR area which is calculated as:
MC DDR region start = Top of DDR - area reserved by Debug Server FW

+ *
+ * Note, as with all data-structures exchanged between software and hardware (be

+ * are interpreted in a binary (rather than numerical) fashion by hardware
+ * blocks (eg. accelerators), then the user should be careful. We illustrate
+ * with an example;
+ *
+ * Suppose the desired behaviour of an accelerator is controlled by the "frc"
+ * field of the FDs that are sent to it. Suppose also that the behaviour desired
+ * by the user corresponds to an "frc" value which is expressed as the literal

+ * value in which 0xfe is the first byte and 0xba is the last byte, and as
+ * hardware is little-endian, this amounts to a 32-bit "value" of 0xbaabedfe. If
+ * the software is little-endian also, this can simply be achieved by setting
+ * frc=0xbaabedfe. On the other hand, if software is big-endian, it should set
+ * frc=0xfeedabba! The best away of avoiding trouble with this sort of thing is
+ * to treat the 32-bit words as numerical values, in which the offset of a field
+ * from the beginning of the first byte (as required or generated by hardware)
+ * is numerically encoded by a left-shift (ie. by raising the field to a
+ * corresponding power of 2). Ie. in the current example, software could set
+ * "frc" in the following way, and it would work correctly on both little-endian
+ * and big-endian operation;

Subject: [PATCH 332/526] zynq: spi: Remove unnecessary error condition
Removed the unnecessary error check from spi_xfer
as the bitlen zero is possible now to deassert the
chip select for which no data is required to be transfered.

Subject: [PATCH 334/526] cmd_sf: Fix problem with "sf update" and unaligned
length
On SoCFPGA, using "sf update" with an non-4byte aligned length leads
to a hangup (and reboot via watchdog). This is because of the unaligned
access in the cadence QSPI driver which is hard to prevent since the
data is written into a 4-byte wide FIFO. This patch fixes this problem
by changing the behavior of the last sector write (not sector aligned).
The new code is even simpler and copies the source data into the temp
buffer and now uses the temp buffer to write the complete sector. So
only one SPI sector write is used now instead of 2 in the old version.

Subject: [PATCH 335/526] mtd: spi: check return value of spi_setup_slave
Need to check value of spi_setup_slave and spi_setup_slave_fdt.
If their return value 'bus' is NULL, there is no need to pass it
to following spi_flash_probe_tail.
If 'bus' is null, the original function flow is as following:
spi_flash_probe
|->spi_setup_slave
|->spi_probe_bus_tail
|->spi_flash_probe_slave
|->spi_free_slave
Alougth check the pointer in spi_free_slave is ok, checking the return value
of spi_setup_slave and spi_setup_slave_fdt is better.
Before this fix:

Subject: [PATCH 336/526] ARM: mxs: Get boot mode from OCRAM
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Reading the boot mode pins after power-up does not necessarily represent the
boot mode used by the ROM loader. For example the state of a pin may have
changed because a recovery switch which was pressed to enter USB mode is
already released after plugging in USB.
The ROM loader stores the value a fixed address in OCRAM. Use this value
instead of reading the boot map pins.
The GLOBAL_BOOT_MODE_ADDR for i.MX28 is taken from an U-Boot patch for the
MX28EVK:
http://repository.timesys.com/buildsources/u/u-boot/u-boot-2009.08/u-boot-2009.08-mx28-201012211513.patch
Leave the boot mode detection for the i.MX23 untouched. Someone has to test
whether the i.MX ROM loader does also store the boot mode in OCRAM and if the
address match.
This patch superseeds my incorrect patch:
ARM: mxs: get boot mode from OTP

DDR3 has a special Precharge power-down mode: fast-exit vs slow-exit.
In slow-exit mode the DLL is off but in some quiescent state that makes it easy
to turn on again in tXPDLL cycles (about 10tCK) vs the full tDLLK (512tCK).
In fast-exist mode the DLL is maintained such that it is ready again in about
3tCK.

+How to use U-boot on Solid-run mx6 hummingboard
+-----------------------------------------------
+
+- Build U-boot for hummingboard:
+
+$ make mrproper
+$ make mx6cuboxi_defconfig
+$ make
+
+This will generate the SPL image called SPL and the u-boot.img.
+
+- Flash the SPL image into the SD card:
+
+sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
+
+- Flash the u-boot.img image into the SD card:
+
+sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
+
+- Insert the SD card in the hummingboard, power it up and U-boot messages
+should come up.

Subject: [PATCH 347/526] imx: ventana: set LTC3676 PMIC to appropriate values
per datasheet
The IMX6 Datasheets specifies that when the IMX6 LDO is enabled
(internal Anatop LDO's for VDD_ARM, VDD_SOC, and VDD_xPU) you need to
provide 1350mV on VDD_ARM_IN and VDD_SOC_IN for IMX6Q@1GHz (Automotive)
and 1275mV for IMX6DL@800MHz (Industrial). While we are still about 50mV
shy on the IMX6Q operating at 1GHz we set it to the max we can and leave it
up to the kernel to implement a regulator driver for the LTC3676 and put
the LDO's in bypass mode which allows us to drop the voltages by 125mV
respectively.

Subject: [PATCH 353/526] imx: ventana: disable IMX6 watchdogs on GW51xx RevA
and RevB
A board level errata causes the IMX6 watchdog to be unstable on the GW51xx
RevA and RevB boards which can cause the watchdog to trip extremely early
(under 5seconds) under certain operating conditions. Disable the watchdog
node in the device-tree to work around this issue.

The min/max of each depends not only on board but on CPU. Simplify by removing
this rarely needed and difficult to maintain feature and just display the
rails and their values.

Subject: [PATCH 362/526] imx: ventana: added DT fixup for GW551x-A video input
The GW551x-A revision does not have the CSI0_DATA_EN pin connected, therefore
we need to make sure that signal is not muxed to the CSI_DATA_EN signal
internally and do so by steering it to the unused GPIO5_IO20.
We do this so that the kernel device-tree can properly define the signal for
RevB and beyond boards that do have this hooked up properly and require it.

that node to avoid such conflicts.

Subject: [PATCH 368/526] imx: ventana: add 'gsc wd' command for enabling and
disabling GSC watchdog
This adds information about the Gateworks System Controller to the gsc command
such as the firmware version, firmware CRC and status of the GSC watchdog
(if its enabled and if its tripped).
Additionally the 'gsc wd' command can be used to enable or disable the
watchdog with the following usage:
gsc wd enable [30|60]
gsc wd disable
Note that the GSC registers are battery-backed by the GSC coincell so once
eanbled, they remain enabled across power-cycles or until either the GSC
firmware has been updated or FLASH has been re-programmed by the Gateworks
JTAG adapter.

Subject: [PATCH 370/526] imx: ventana: use hdmiinfmt env var to override HDMI
capture format
The HDMI receiver used on the GW54xx and GW551x has a 16bit video data bus
interconnect between it and the IMX6 CSI. This can be used in two different
modes, each having advantages and disadvantages. Allow the hdmiinfmt env
var to specify which format is desired (yuv422smp or yuv422bt656).

Subject: [PATCH 371/526] imx: ventana: set HDMI video in to yuv422bt656 for
GW551x-A
The initial revision of the GW551x does not connect enough signals between
the HDMI receiver and the IMX6 CSI for 16bit capture mode necessary for
yuv422smp capture. Future revisions will, but for the initial rev force it
to yuv422bt656 mode which requires an 8bit video data bus.

Subject: [PATCH 381/526] unzip: add gzwrite command to write compressed image
to block device
Add gzwrite command to write gzip-compressed images to block devices.
Input must be gzip-compressed according to RFC1952, since the crc
and file size in the trailer will be confirmed during operation.
The decompressed file size must be specified on the command line
for images with decompressed sizes >= 4GiB because the trailer
only contains the low 32 bits of the original file size.

Subject: [PATCH 386/526] cmd_scsi: Enable SoC AHCI device on platforms with
PCI
Current driver assumes the AHCI is connected to PCI, this is not
true on some SoCs, e.g. LS1021A, which has PCI but the AHCI is
in SoC. This patch will enable embedded AHCI devices on platforms
with PCI.
PCI AHCI devices still can be used by commenting CONFIG_SCSI_AHCI_PLAT
option in head file.

Subject: [PATCH 387/526] dm: core: add internal functions for getting the
device without probe
This commit extends the uclass-internal functions by:
- uclass_find_first_device()
- uclass_find_next_device()
For both functions, the returned device is not probed.
After some cleanup, the above functions are called by:
- uclass_first_device()
- uclass_next_device()
for which, the returned device is probed.

Subject: [PATCH 388/526] dm: core: Extend struct udevice by '.uclass_platdata'
field.
This commit adds 'uclass_platdata' field to 'struct udevice', which
can be automatically allocated at bind. The allocation size is defined
in 'struct uclass_driver' as 'per_device_platdata_auto_alloc_size'.
New device's flag is added: DM_FLAG_ALLOC_UCLASS_PDATA, which is used
for memory freeing at device unbind method.
As for other udevice's fields, a complementary function is added:
- dev_get_uclass_platdata()

Subject: [PATCH 389/526] dm: test: Add tests for device's uclass platform data
This test introduces new test structure type:dm_test_perdev_uc_pdata.
The structure consists of three int values only. For the test purposes,
three pattern values are defined by enum, starting with TEST_UC_PDATA_INTVAL1.
This commit adds two test cases for uclass platform data:
- Test: dm_test_autobind_uclass_pdata_alloc - this tests if:
* uclass driver sets: .per_device_platdata_auto_alloc_size field
* the devices's: dev->uclass_platdata is non-NULL
- Test: dm_test_autobind_uclass_pdata_valid - this tests:
* if the devices's: dev->uclass_platdata is non-NULL
* the structure of type 'dm_test_perdev_uc_pdata' allocated at address
pointed by dev->uclass_platdata. Each structure field, should be equal
to proper pattern data, starting from .intval1 == TEST_UC_PDATA_INTVAL1.

This commit extends the driver model uclass's API by function:

And this function returns the device if:
- uclass with given ID, exists,
- device with exactly given name(dev->name), exists.
The returned device is not activated - need to be probed before use.
Note:
This function returns the first device, which name is equal
to the given one. This means, that using this function you must
assume, that the device name is unique in the given uclass's ID
device list.
uclass-internal.h: cleanup - move the uclass_find_device_by_seq()
declaration and description, near the other uclass_find*() functions.

Subject: [PATCH 394/526] dm: core: device: add function: dev_get_uclass_name()
This commit extends the driver model device's API by function:
- dev_get_uclass_name()
And this function returns the device's uclass driver name if:
- given dev pointer, is non_NULL
otherwise, the NULL pointer is returned.

uclass_get_device_tail()
Uclass API provides a few functions for get/find the device.
To provide a complete function set of uclass-internal functions,
for use by the drivers, the function uclass_get_device_tail()
should be non-static.

Since a device can have children in the same uclass as itself, we need
to handle unbinding carefully: we must allow that unbinding a device in a
uclass may cause another device in the same uclass to be unbound.
Adjust the code to cope.

Zero only the global_data fields that are required for the test to function.

Subject: [PATCH 402/526] exynos: sandbox: ti: Add SPDX license identifiers and
notes
For some files I neglected to add a license. Rectify this:
arch/arm/dts/exynos4210-pinctrl-uboot.dtsi
arch/arm/dts/exynos4x12-pinctrl-uboot.dtsi
arch/arm/dts/exynos5250-pinctrl-uboot.dtsi
arch/arm/dts/exynos54xx-pinctrl-uboot.dtsi
arch/arm/dts/s5pc100-pinctrl.dtsi
arch/arm/dts/s5pc110-pinctrl.dtsi
This file came from Linux and has no license information there, so add a
comment to that effect:
arch/sandbox/include/asm/bitops.h
This file also came from Linux - presumably someone from TI could add the
license:
include/dt-bindings/pinctrl/omap.h

Subject: [PATCH 408/526] board/BuR/tseries: reactivate NAND-board
The NAND-version has been become a bit orphan.
Now we need to reactivate it, so bring necessary things:
- loading devicetree
- switch control signal to correct pins
- setup pinmux
- default-environment
up to date.

Subject: [PATCH 410/526] vexpress64: use DM for all vexpress64 boards
Commit d8bafe1310487ba0e0785997726b4792072178d3
"ARMv8: enable DM in vexpress64 board" only enabled DM
for the simulated vexpress64 board (FVP) with the
hardcoded clock value for the simulated board, causing
a console regression on the Juno board which was using
a different clock setting.
Fix this by enabling DM for all vexpress64 boards,
defining the clock frequency per-board, deleting the
static array of PL01x ports from the config file and
relying solely on the port defined in the boardfile
using platform data.

These is a growing trend to license DT files dual GPL and X11
especially in the Linux community. It allows easier reuse of
device trees for other software projects.
This commit prepares for doing so in U-Boot too, since DT files are
often copied from the kernel to U-Boot.

Subject: [PATCH 414/526] ARM: integrator: move board select into
mach-integrator/Kconfig
The board/SoC select menu in arch/arm/Kconfig is still cluttered.
Add ARCH_INTEGRATOR into arch/arm/Kconfig and move the board select
under arch/arm/mach-integrator.

Subject: [PATCH 415/526] ARM: integrator: split board select into AP/CP select
and CM select
Select integrator boards by the combination of platform select (AP/CP)
and core module select (CM720T, CM920T, ...).
This allows us to remove CONFIG_SYS_EXTRA_OPTIONS and make Kconfig
much cleaner.

Subject: [PATCH 419/526] cmd_led: Extend led command to support blinking and
more leds
This patch extends the U-Boot "led" command to support automatic blinking
by setting a blink frequency in milliseconds. Additionally the number of
supported LEDs is increased to 6 (0...5).
This will be used by the PCA9551 LED driver.

Subject: [PATCH 422/526] dm: core: Remove unbind operations when not required
The CONFIG_DM_DEVICE_REMOVE option takes out code related to removing
devices. It should also remove the 'unbind' code since if we cannot
remove we probably don't need to unbind.

remove or unbind devices and do not expect to get errors when binding

Subject: [PATCH 429/526] fdt: Add an option to disable device tree in SPL
Some boards cannot support device tree due to lack of memory. Add an option
to allow these boards to continue to work (and even use driver model).
This is a 'negative' option since most boards are expected to support device
tree in SPL.

Subject: [PATCH 435/526] driver/fsl_ifc: Add support to finalize CS1, CS3
address binding
For fsl-lsch3, IFC is binded with address within 32-bit at fist.
After u-boot relocates to DDR, CS1, CS3 can be binded to higher
address to support large space.

Subject: [PATCH 437/526] driver/i2c/mxc: Enable I2C bus 3 and 4
Some SoCs have more than two I2C busses. Instead of adding ifdef
to the driver, macros are put into board header file where
CONFIG_SYS_I2C_MXC is defined.

Subject: [PATCH 438/526] drivers/ddr/fsl: Update DDR driver for DDR4
Add/update registers for DDR4, including DQ mappings. Allow raw timing
method used for all controllers. Update mode_9 register to 0x500 for
improved stability. Check DDR controller version number individually
in case a SoC has multiple DDR controllers of different versions.
Increase read-write turnaround for DDR4 high speeds.

Subject: [PATCH 439/526] driver/ddr/fsl: Fix driver to support empty first
slot
CS0 was not allowed to be empty by u-boot driver in the past to simplify
the driver. This may be inconvenient for some debugging. This patch lifts
the restrictions. Controller interleaving still requires CS0 populated.

Subject: [PATCH 440/526] driver/ddr/fsl: Add built-in memory test for DDR4
driver
Add built-in memory test to catch errors after DDR is initialized, before
any other transactions. To enable this test, define CONFIG_FSL_DDR_BIST.
An environmental variable "ddr_bist" is checked before starting test.
It takes a while (several seconds) depending on system memory size.

Subject: [PATCH 445/526] armv8/ls2085a: Update common header file
ls2085a_common.h contains hard-coded information for NOR/NAND flash,
I2C, DDR, etc. These are platform specific. Move them out of common
header file and placed into respective board header files.
Move TEXTBASE to 1MB offset to fit NOR flash with up to 1MB sector
size.
Enable command auto complete. Update prompt symbol. Set fdt_high to
0xa0000000 because Linux requires that the fdt be 8-byte aligned
and below 512 MiB. Besides ensuring compliance with the 512 MiB
limit, this avoids problems with the dtb being misaligned within
the FIT image.
Change the MC FW, MC DPL and Debug server NOR addresses in compliance
with the NOR flash layouts for 128MB flash.
Add PCIe macros. Enable "loadb" command. Disable debug server.

Subject: [PATCH 447/526] armv8/ls2085a: Fix generic timer clock source
The timer clock is system clock divided by 4, not fixed 12MHz.
This is common to the SoC, not board specific. Primary core is
fixed when u-boot still runs in board_f. Secondary cores are
fixed by reading a variable set by u-boot.

Subject: [PATCH 450/526] armv8/fsl-lsch3: Update early MMU table
During booting, IFC is mapped to low region. After booting up, IFC is
remapped to high region for larger space. The environmental variables are
also stored at high region. In order to read the variables during booting,
a virtual mapping is required.
Cache was enabled for entire IFC space before. Actually the first two
entries are big enough (4MB) to cover the boot code and environmental
variables. Remove extra entries. Move OCRAM entry out of ifdef.

Subject: [PATCH 454/526] driver/ldpaa_eth: Update ldpaa ethernet driver
Fix flush_dcache_range() input parameter to use start and end addresses.
Change ethernet interface name to DPNI. Update entry criteria for
ldpaa_eth_stop. Ethernet stack first stop the device before performing
next operation. At the time of Ethernet driver registration,
net_dev->state is set as ETH_STATE_INIT So take care net_dev->state as
ETH_STATE_INIT in ldpaa_eth_stop.
Undef CONFIG_PHYLIB temorarily because ldpaa_eth driver currently does
not support PHYLIB.
Instead of clearing pull descriptor one time, clear it before issuing any
volatile dequeue command.
Volatile command does not return frame immidiately, wait till a frame
is available in DQRR. This frame can be valid or expired.
Flush buffer before releasing to BMan ensure the core does not have any
cachelines that the WRIOP will DMA to.

Subject: [PATCH 457/526] drivers/fsl-mc: Changed MC firmware loading for new
boot architecture
Changed MC firmware loading to comply with the new MC boot architecture.
Flush D-cache hierarchy after loading MC images. Add environment
variables "mcboottimeout" for MC boot timeout in milliseconds,
"mcmemsize" for MC DRAM block size. Check MC boot status before calling
flib functions.

From cd348efa6c8c38cc95495a34d784f9ea159ca41d Mon Sep 17 00:00:00 2001
From: Shaohui Xie <Shaohui.Xie@freescale.com>
Date: Fri, 20 Mar 2015 19:28:19 -0700
Subject: [PATCH 458/526] net/memac_phy: reuse driver for little endian SoCs
The memac for PHY management on little endian SoCs is similar on big
endian SoCs, so we modify the driver by using I/O accessor function to
handle the endianness, so the driver can be reused on little endian
SoCs, we introduce CONFIG_SYS_MEMAC_LITTLE_ENDIAN for little endian
SoCs, if the CONFIG_SYS_MEMAC_LITTLE_ENDIAN is defined, the I/O access
is little endian, if not, the I/O access is big endian. Move fsl_memac.h
out of powerpc include.

Subject: [PATCH 460/526] driver/ldpaa: Add support of WRIOP static data
structure
Wire rate IO Processor (WRIOP) provide support of receive and transmit
ethernet frames from the ethernet MAC. Here Each WRIOP block supports
upto 64 DPMACs.
Create a house keeping data structure to support upto 16 DPMACs and
store external phy related information.

+Summary
+=======
+This README assumes you have read README.da850. It contains some additional
+information specific to building the omapl138-lcdk. The AIS file as generated
+by the build is, currently, not useable due to differences in the flash
+available on this board, as compared to the da850evm boards.
+
+Flash Differences
+=================
+Refer to the discussion in [1] for more detail - basically the da850evm uses
+SPI flash whereas the lcdk uses NAND flash to store the bootloader, and
+the support isn't there in the SPL code.
+
+It should be possible to add the support in the SPL code should someone be
+sufficiently motivated.
+
+Using the built image
+=====================
+The output image to use is u-boot.bin. This needs to be converted to an
+AIS file as described in [1] and then flashed using the utitilty linked to
+there and also described in README.da850. You _may_ be able to write using
+u-boot itself, but the commands in README.da850 won't work as they write to
+SPI rather than NAND.

From: Xiang Wang <wangx@marvell.com>
Date: Mon, 23 Mar 2015 17:56:58 -0500
Subject: [PATCH 464/526] gpio: mvmfp: support newer MFP bit definitions
1. The bits 11..10 for mfp driver strength is only valid for
aspen and old xscale family, for newer Marvell chip, this range
has been moved to 12..11.
2. add sleep bit support

Subject: [PATCH 467/526] ARM: DRA7: Set serial number environment variable
This patch populates serial number environment variable from
die_id_0 and die_id_1 register values for DRA7xx boards.
The function is added in omap common code so that this can be re-used.
Serial# environment variable will be useful to show correct
information in "fastboot devices" commands.

Subject: [PATCH 470/526] fastboot: ARM: OMAP5: Enable reboot-bootloader
Implemented fb_set_reboot_flag() for OMAP5 to set
an environment variable 'dofastboot' when reboot-bootloader called.
This environment variable will be checked in boot command and fastboot
will be called if the variable is set.
If the bootcmd env variable of OMAP5 common is overwritten with board-specific
command, then these changes will not apply.
This was originally intended for DRA7 platform, but now applies to all OMAP5.

Subject: [PATCH 471/526] m68k: add architecture-specific u-boot.lds
Add architecture-specific u-boot.lds and remove all board-specific
u-boot.lds.
All the .text customization that was board-specific have been
moved inside the related include/configs, inside a
LDS_BOARD_TEXT define.

Subject: [PATCH 473/526] rtc: Set valid date after reset
Some RTC chips tend to set garbage date after reset.
This patch sets the date to 2000-01-01 00:00 immediatelly
after the RTC chip reset is issued using the "date reset"
command.

Subject: [PATCH 475/526] ARM: vf610: Move DDR3 initialization to imx-common
In order to avoid code duplication, move the DDR3 initialization to the
common place under imx-common. Currently ROW_DIFF and COL_DIFF can be
chosen from the board file. The JEDEC timings are specified using a
common ddr3_jedec_timings structure.

Subject: [PATCH 477/526] ARM: vf610: Add SoC and CPU type detection
Vybrid product family consists of several rather similar SoC which
can be determined by softare during boot time. This allows use of
variable ${soc} for Linux device tree files. Detect VF5xx CPU's by
reading the CPU count register. We can determine the second number
of the CPU type (VF6x0) which indicates the presence of a L2 cache.

Enables caches which provides a rather huge speedup of the boot loader.
Also mark the on-chip RAM as cachable since this is the area U-Boot runs

Subject: [PATCH 479/526] ARM: vf610: Initial integration for Colibri VF50/VF61
This adds initial support for Colibri VF50/VF61 based on Freescale
Vybrid SoC.
- CPU clocked at 396/500 MHz
- DDR3 at 396MHz
- for VF50, use PLL2 as memory clock (synchronous mode)
- for VF61, use PLL1 as memory clock (asynchronous mode)
- Console on UART0 (Colibri UART_A)
- Ethernet on FEC1
- PLL5 based RMII clocking (E.g. No external crystal)
- UART_A and UART_C I/O muxing
- Boot from NAND by default
Tested on Colibri VF50/VF61 booting using serial loader over UART.

From: Jaiprakash Singh <b44839@freescale.com>
Date: Fri, 20 Mar 2015 19:28:27 -0700
Subject: [PATCH 483/526] driver/ifc: Add 64KB page support
IFC has two register pages.Till IFC version 1.4 each
register page is 4KB each.But IFC ver 2.0 register page
size is 64KB each.IFC regiters structure is break into
two viz FCM and RUNTIME.FCM(Flash control machine) registers
are defined in PAGE0 and controls IFC generic functionality.
RUNTIME registers are defined in PAGE1 and controls NAND and
GPCM funcinality.
FCM and RUNTIME structures defination is common for IFC
version 1.4 and 2.0.

+Booting from NAND
+-------------------
+Booting from NAND requires two images, RCW and u-boot-with-spl.bin.
+The difference between NAND boot RCW image and NOR boot image is the PBI
+command sequence. Below is one example for PBI commands for QDS which uses
+NAND device with 2KB/page, block size 128KB.
+
+1) CCSR 4-byte write to 0x00e00404, data=0x00000000
+2) CCSR 4-byte write to 0x00e00400, data=0x1800a000
+The above two commands set bootloc register to 0x00000000_1800a000 where
+the u-boot code will be running in OCRAM.
+
+3) Block Copy: SRC=0x0107, SRC_ADDR=0x00020000, DEST_ADDR=0x1800a000,
+BLOCK_SIZE=0x00014000
+This command copies u-boot image from NAND device into OCRAM. The values need
+to adjust accordingly.
+
+SRC should match the cfg_rcw_src, the reset config pins. It depends
+ on the NAND device. See reference manual for cfg_rcw_src.
+SRC_ADDR is the offset of u-boot-with-spl.bin image in NAND device. In
+ the example above, 128KB. For easy maintenance, we put it at
+ the beginning of next block from RCW.
+DEST_ADDR is fixed at 0x1800a000, matching bootloc set above.
+BLOCK_SIZE is the size to be copied by PBI.
+
+RCW image should be written to the beginning of NAND device. Example of using
+u-boot command
+
+nand write <rcw image in memory> 0 <size of rcw image>
+
+To form the NAND image, build u-boot with NAND config, for example,
+ls2085aqds_nand_defconfig. The image needed is u-boot-with-spl.bin.
+The u-boot image should be written to match SRC_ADDR, in above example 0x20000.
+
+nand write <u-boot image in memory> 200000 <size of u-boot image>
+
+With these two images in NAND device, the board can boot from NAND.

Subject: [PATCH 490/526] fdt: Fix handling of paths with options in them
After syncing the sunxi dts files with the upstream kernel dm/fdt sunxi
builds would no longer boot.
The problem is that stdout-path is now set like this in the upstream dts
files: stdout-path = "serial0:115200n8". The use of options in of-paths,
either after an alias name, or after a full path, e.g. stdout-path =
"/soc@01c00000/serial@01c28000:115200", is standard of usage, but something
which the u-boot dts code so far did not handle.
This commit fixes this, adding support for both path formats.

Subject: [PATCH 495/526] mx6cuboxi: Introduce multi-SoC support
Cubox-i and Hummingboard support several MX6 SoCs: mx6solo, mx6dual-lite,
mx6dual and mx6quad. Add support for the different SoC/memory sizes
combinations.
DDR initialization values were extracted from Solid-run internal U-boot.
Tested on a CuBox-i4Pro, HummingBoard-i2eX and HummingBoard-i1.

Subject: [PATCH 499/526] spi: omap3: Fix timeout handling
The timeout value is never reset during the transfer. This means that when
transferring more data we eventually trigger the timeout.
This was reported on the mailing list:

Subject: [PATCH 501/526] dm: sf: Make SST flash write op work again
With SPI flash moving to driver model, commit fbb0991 "dm: Convert
spi_flash_probe() and 'sf probe' to use driver model" ignored the
SST flash-specific write op (byte program & word program), which
actually broke the SST flash from wroking.
This commit makes SST flash work again under driver model, by adding
SST flash-specific handling in the spi_flash_std_write().

become the sector_size finally.

Subject: [PATCH 505/526] dm: core: Correct bug introduced in
uclass_first/next_device()
These functions now rely on uclass_find_first/next_device() and assume that
they will either return failure (-ve error code) or a device. In fact,
coming to the end of a list is not considered failure and they return 0
in that case.
The logic to deal with this was replaced in commit acb9ca2a with just using
uclass_get_device_tail(). Add back the missing logic. This bug was
caught by unit tests but since they were broken for other reasons at the
time, this was not noticed.

Subject: [PATCH 510/526] zynq: Add Zynq PicoZed board support
The PicoZed is a System-on-Module board which is marketed as part of
the ZedBoard/MicroZed/etc. collection. It includes a Zynq-7000
processor.
This patch adds support that covers all the variants of the PicoZed
including the SKUs with Z7010/Z7020 and Z7015/Z7030 Zynq chips. This
patch set however only covers support for the System-on-Module and does
not cover any extra components that are available on carrier boards
(except those that are fanned out of the module itself).
More information on this board, its variants and available carrier
boards is available at: http://zedboard.org/product/picozed

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We are about to change the location for ps7_init files, breaking the
current work-flows. It is good time to drop the legacy ps7_init.c/h
support.
Going forward, please use ps7_init_gpl.c/h all the time.
If you are still using old Xilinx tools that are only able to
generate ps7_init.c/h, rename them into ps7_init_gpl.c/h.
