of display-timings node to select timings for a specific display.
This is useful if a device-tree has configurations for multiple
display timings for undetectable displays.

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.

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

Since commit 79d75d75 (ARM: move -march=* and -mtune= options to
arch/arm/Makefile), all the Tegra boards are broken because the SPL
is built for ARMv7.

Insert Tegra-specific code to arch/arm/Makefile to set compiler
flags for an earlier ARM architecture.

Note:
The v1 patch for commit 79d75d75 *was* correct when it was
submitted.  Notice it was originally written for multi .config
configuration where Kconfig set CONFIG_CPU_V7/CONFIG_CPU_ARM720T for
Tegra U-Boot Main/SPL, respectively.  But, until it was merged into
the mainline, commit e02ee254 (kconfig: switch to single .config
configuration) had been already applied there.

The ARM reference designs all use a special flash image format
that stores a footer (two versions exist) at the end of the last
erase block of the image in flash memory.

Version one of the footer is indicated by the magic number
0xA0FFFF9F at 12 bytes before the end of the flash block and
version two is indicated by the magic number 0x464F4F54 0x464C5348
(ASCII for "FLSHFOOT") in the very last 8 bytes of the erase block.

This command driver implements support for both versions of the
AFS images (the name comes from the Linux driver in drivers/mtd/afs.c)
and makes it possible to list images and load an image by name into
the memory with these commands:

afs - lists flash contents
afs load <image> - loads image to address indicated in the image
afs load <image> <addres> - loads image to a specified address

This image scheme is used on the ARM Integrator family, ARM
Versatile family, ARM RealView family (not yet supported in U-Boot)
and ARM Versatile Express family up to and including the new
Juno board for 64 bit development.

The ubi check command is expected to not fail and just check whether
a volume exist or not. Currently, when a volume does not exist, the
command fails which leads to an error:
"exit not allowed from main input shell."

Use 1 to indicate that a volume does not exist. This allows to use
ubi check in an if statement, e.g.
if ubi check rootfs; then; echo "exists"; else; echo "not there"; fi

This is important to have entry point in the beginning of .text section
because it allows simple loading and execution of U-Boot.

For example pre-bootloader loads U-Boot in memory starting from offset
0x81000000 and then just jumps to the same address.

Otherwise pre-bootloader would need to find-out where entry-point is. In
its turn if it deals with binary image of U-Boot there's no way for
pre-bootloader to get required value.

There're 2 versions of motherboards that could be used in ARC SDP.
The only important difference for U-Boot is different NAND IC in use:
 [1] v2 board (we used to support up until now) sports MT29F4G08ABADAWP
while
 [2] v3 board sports MT29F4G16ABADAWP

They are almost the same except data bus width 8-bit in [1] and 16-bit
in [2]. And for proper support of 16-bit data bus we have to pass
NAND_BUSWIDTH_16 option to NAND driver core - which we do now knowing
board type we're running on.

Since commit 326a6823 (malloc_f: enable SYS_MALLOC_F by default
if DM is on), Zynq MMC boot hangs up after printing the following:

    U-Boot SPL 2015.04-rc5-00053-gadcc570 (Apr 08 2015 - 12:59:11)
    mmc boot
    reading system.dtb

Prior to commit 326a6823, Zynq boards enabled CONFIG_DM, but
not CONFIG_SYS_MALLOC_F.  That commit forcibly turned on
CONFIG_SYS_MALLOC_F.  I have not figured out the root cause, but
anyway it looks like CONFIG_SYS_MALLOC_F gave a bad impact on the
Zynq MMC boot.

We are planning to have the v2015.04 release in a few days.
I know this is a defensive fixup, but what I can do now is to add
   # CONFIG_SYS_MALLOC_F is not set
to every Zynq defconfig file to get back the original behavior.

  - ZC706 board

The CPU and Reset cause lines appear twice.

Initially mx53 boots at 800MHz, then at a later point the PMIC is configured via
I2C to raise the CPU voltage so that it can run at 1GHz.

To avoid such misleading double printings, disable printing cpu info for now.
