NOP PHY driver
This driver is used to stub PHY operations in a driver (USB, SATA).
This is useful when the 'client' driver (USB, SATA, ...) uses the PHY framework
and there is no actual PHY harwdare to drive.
Required properties:
- compatible : must contain "nop-phy"
- #phy-cells : must contain <0>
Example:
nop_phy {
compatible = "nop-phy";
#phy-cells = <0>;
};

STMicroelectronics STM32 USB HS PHY controller
The STM32 USBPHYC block contains a dual port High Speed UTMI+ PHY and a UTMI
switch. It controls PHY configuration and status, and the UTMI+ switch that
selects either OTG or HOST controller for the second PHY port. It also sets
PLL configuration.
USBPHYC
|_ PLL
|
|_ PHY port#1 _________________ HOST controller
| _ |
| / 1|________________|
|_ PHY port#2 ----| |________________
| \_0| |
|_ UTMI switch_______| OTG controller
Phy provider node
=================
Required properties:
- compatible: must be "st,stm32mp1-usbphyc"
- reg: address and length of the usb phy control register set
- clocks: phandle + clock specifier for the PLL phy clock
- #address-cells: number of address cells for phys sub-nodes, must be <1>
- #size-cells: number of size cells for phys sub-nodes, must be <0>
Optional properties:
- assigned-clocks: phandle + clock specifier for the PLL phy clock
- assigned-clock-parents: the PLL phy clock parent
- resets: phandle + reset specifier
Required nodes: one sub-node per port the controller provides.
Phy sub-nodes
==============
Required properties:
- reg: phy port index
- phy-supply: phandle to the regulator providing 3V3 power to the PHY,
see phy-bindings.txt in the same directory.
- vdda1v1-supply: phandle to the regulator providing 1V1 power to the PHY
- vdda1v8-supply: phandle to the regulator providing 1V8 power to the PHY
- #phy-cells: see phy-bindings.txt in the same directory, must be <0> for PHY
port#1 and must be <1> for PHY port#2, to select USB controller
Example:
usbphyc: usb-phy@5a006000 {
compatible = "st,stm32mp1-usbphyc";
reg = <0x5a006000 0x1000>;
clocks = <&rcc_clk USBPHY_K>;
resets = <&rcc_rst USBPHY_R>;
#address-cells = <1>;
#size-cells = <0>;

If a "SPDX-License-Identifier:" line references more than one Unique
License Identifier, then this means that the respective file can be
used under the terms of either of these licenses, i. e. with
SPDX-License-Identifier: GPL-2.0+ BSD-3-Clause
SPDX-License-Identifier: GPL-2.0+ OR BSD-3-Clause
you can choose between GPL-2.0+ and BSD-3-Clause licensing.
We use the SPDX Unique License Identifiers here; these are available

License identifier syntax
-------------------------
1. Placement:
The SPDX license identifier in U-Boot files shall be added at the first
possible line in a file which can contain a comment. For the majority
or files this is the first line, except for scripts which require the
'#!PATH_TO_INTERPRETER' in the first line. For those scripts the SPDX
identifier goes into the second line.
|
2. Style:
The SPDX license identifier is added in form of a comment. The comment
style depends on the file type::
C source: // SPDX-License-Identifier: <SPDX License Expression>
C header: /* SPDX-License-Identifier: <SPDX License Expression> */
ASM: /* SPDX-License-Identifier: <SPDX License Expression> */
scripts: # SPDX-License-Identifier: <SPDX License Expression>
.rst: .. SPDX-License-Identifier: <SPDX License Expression>
.dts{i}: // SPDX-License-Identifier: <SPDX License Expression>
If a specific tool cannot handle the standard comment style, then the
appropriate comment mechanism which the tool accepts shall be used. This
is the reason for having the "/\* \*/" style comment in C header
files. There was build breakage observed with generated .lds files where
'ld' failed to parse the C++ comment. This has been fixed by now, but
there are still older assembler tools which cannot handle C++ style
comments.
|
3. Syntax:
A <SPDX License Expression> is either an SPDX short form license
identifier found on the SPDX License List, or the combination of two
SPDX short form license identifiers separated by "WITH" when a license
exception applies. When multiple licenses apply, an expression consists
of keywords "AND", "OR" separating sub-expressions and surrounded by
"(", ")" .
License identifiers for licenses like [L]GPL with the 'or later' option
are constructed by using a "+" for indicating the 'or later' option.::
// SPDX-License-Identifier: GPL-2.0+
// SPDX-License-Identifier: LGPL-2.1+
WITH should be used when there is a modifier to a license needed.
For example, the linux kernel UAPI files use the expression::
// SPDX-License-Identifier: GPL-2.0 WITH Linux-syscall-note
// SPDX-License-Identifier: GPL-2.0+ WITH Linux-syscall-note
Other examples using WITH exceptions found in the linux kernel are::
// SPDX-License-Identifier: GPL-2.0 WITH mif-exception
// SPDX-License-Identifier: GPL-2.0+ WITH GCC-exception-2.0
Exceptions can only be used with particular License identifiers. The
valid License identifiers are listed in the tags of the exception text
file.
OR should be used if the file is dual licensed and only one license is
to be selected. For example, some dtsi files are available under dual
licenses::
// SPDX-License-Identifier: GPL-2.0 OR BSD-3-Clause
Examples from U-Boot for license expressions in dual licensed files::
// SPDX-License-Identifier: GPL-2.0 OR MIT
// SPDX-License-Identifier: GPL-2.0+ OR BSD-3-Clause
AND should be used if the file has multiple licenses whose terms all
apply to use the file. For example, if code is inherited from another
project and permission has been given to put it in U-Boot, but the
original license terms need to remain in effect::
// SPDX-License-Identifier: (GPL-2.0 WITH Linux-syscall-note) AND MIT
Another other example where both sets of license terms need to be
adhered to is::
// SPDX-License-Identifier: GPL-1.0+ AND LGPL-2.1+

- Legacy I2C Support: CONFIG_HARD_I2C
NOTE: It is intended to move drivers to CONFIG_SYS_I2C which
provides the following compelling advantages:
- more than one i2c adapter is usable
- approved multibus support
- better i2c mux support
** Please consider updating your I2C driver now. **
These enable legacy I2C serial bus commands. Defining
CONFIG_HARD_I2C will include the appropriate I2C driver
for the selected CPU.
This will allow you to use i2c commands at the u-boot
command line (as long as you set CONFIG_CMD_I2C in
CONFIG_COMMANDS) and communicate with i2c based realtime
clock chips. See common/cmd_i2c.c for a description of the
command line interface.
CONFIG_HARD_I2C selects a hardware I2C controller.
There are several other quantities that must also be
defined when you define CONFIG_HARD_I2C.
In both cases you will need to define CONFIG_SYS_I2C_SPEED
to be the frequency (in Hz) at which you wish your i2c bus
to run and CONFIG_SYS_I2C_SLAVE to be the address of this node (ie
the CPU's i2c node address).
Now, the u-boot i2c code for the mpc8xx
(arch/powerpc/cpu/mpc8xx/i2c.c) sets the CPU up as a master node
and so its address should therefore be cleared to 0 (See,
eg, MPC823e User's Manual p.16-473). So, set
CONFIG_SYS_I2C_SLAVE to 0.
CONFIG_SYS_I2C_INIT_MPC5XXX
When a board is reset during an i2c bus transfer
chips might think that the current transfer is still
in progress. Reset the slave devices by sending start
commands until the slave device responds.

"embedded" in the text segment with the U-Boot code. This
happens usually with "bottom boot sector" or "top boot
sector" type flash chips, which have several smaller
sectors at the start or the end. For instance, such a
layout can have sector sizes of 8, 2x4, 16, Nx32 kB. In
such a case you would place the environment in one of the

memory for the RAM copy of the environment.
It may also save flash memory if you decide to use this

since then the remainder of the flash sector could be used
for U-Boot code. It should be pointed out that this is

Define this to a string that is the mtd partition containing the UBI.
- CONFIG_ENV_UBI_VOLUME:
Define this to the name of the volume that you want to store the
environment in.
- CONFIG_ENV_UBI_VOLUME_REDUND:
Define this to the name of another volume to store a second copy of
the environment in. This will enable redundant environments in UBI.
It is assumed that both volumes are in the same MTD partition.
- CONFIG_UBI_SILENCE_MSG
- CONFIG_UBIFS_SILENCE_MSG
You will probably want to define these to avoid a really noisy system
when storing the env in UBI.
- CONFIG_ENV_IS_IN_FAT:
Define this if you want to use the FAT file system for the environment.
- FAT_ENV_INTERFACE:
Define this to a string that is the name of the block device.
- FAT_ENV_DEVICE_AND_PART:
Define this to a string to specify the partition of the device. It can
be as following:
"D:P", "D:0", "D", "D:" or "D:auto" (D, P are integers. And P >= 1)
- "D:P": device D partition P. Error occurs if device D has no
partition table.
- "D:0": device D.
- "D" or "D:": device D partition 1 if device D has partition
table, or the whole device D if has no partition
table.
- "D:auto": first partition in device D with bootable flag set.
If none, first valid partition in device D. If no
partition table then means device D.
- FAT_ENV_FILE:
It's a string of the FAT file name. This file use to store the
environment.
- CONFIG_FAT_WRITE:
This should be defined. Otherwise it cannot save the environment file.
- CONFIG_ENV_IS_IN_MMC:
Define this if you have an MMC device which you want to use for the
environment.
- CONFIG_SYS_MMC_ENV_DEV:
Specifies which MMC device the environment is stored in.
- CONFIG_SYS_MMC_ENV_PART (optional):
Specifies which MMC partition the environment is stored in. If not
set, defaults to partition 0, the user area. Common values might be
1 (first MMC boot partition), 2 (second MMC boot partition).
- CONFIG_ENV_OFFSET:
- CONFIG_ENV_SIZE:
These two #defines specify the offset and size of the environment
area within the specified MMC device.
If offset is positive (the usual case), it is treated as relative to
the start of the MMC partition. If offset is negative, it is treated
as relative to the end of the MMC partition. This can be useful if
your board may be fitted with different MMC devices, which have
different sizes for the MMC partitions, and you always want the
environment placed at the very end of the partition, to leave the
maximum possible space before it, to store other data.
These two values are in units of bytes, but must be aligned to an
MMC sector boundary.
- CONFIG_ENV_OFFSET_REDUND (optional):
Specifies a second storage area, of CONFIG_ENV_SIZE size, used to
hold a redundant copy of the environment data. This provides a
valid backup copy in case the other copy is corrupted, e.g. due
to a power failure during a "saveenv" operation.
This value may also be positive or negative; this is handled in the
same way as CONFIG_ENV_OFFSET.
This value is also in units of bytes, but must also be aligned to
an MMC sector boundary.
- CONFIG_ENV_SIZE_REDUND (optional):
This value need not be set, even when CONFIG_ENV_OFFSET_REDUND is
set. If this value is set, it must be set to the same value as
CONFIG_ENV_SIZE.
- CONFIG_SYS_SPI_INIT_OFFSET
Defines offset to the initial SPI buffer area in DPRAM. The
area is used at an early stage (ROM part) if the environment
is configured to reside in the SPI EEPROM: We need a 520 byte
scratch DPRAM area. It is used between the two initialization
calls (spi_init_f() and spi_init_r()). A value of 0xB00 seems
to be a good choice since it makes it far enough from the
start of the data area as well as from the stack pointer.
Please note that the environment is read-only until the monitor
has been relocated to RAM and a RAM copy of the environment has been
created; also, when using EEPROM you will have to use getenv_f()
created; also, when using EEPROM you will have to use env_get_f()
until then to read environment variables.
The environment is protected by a CRC32 checksum. Before the monitor
