This patch prevents from the situation where we may end up with garbage
displayed on the LCD panel.
Such situation occurs when one performs "reboot -f" in Linux and then
stop in U-boot (or observe the garbage on the screen during boot up).
To prevent from such situation - the PWM pin is configured as GPIO and set
to LOW.

According to the Cortex-A7 TRM, for ACTLR.SMP bit "You must ensure this bit
is set to 1 before the caches and MMU are enabled, or any cache and TLB
maintenance operations are performed".
ROM sets this bit in normal boot flow, but when in serial download mode,
it is not set.
Here we add it in u-boot as a common flow for all i.MX cortex-a7 platforms,
including mx7d, mx6ul/ull and mx7ulp.

On its enter we will check GPT and restore it if needed.

Test case:
The fitImage gets corrupted:
truncate -c -s 3M fitImage
run tftp_mmc_fitImg
setenv boot_os y
reset
[board shall hang in SPL with
"Trying to boot from MMC1" information]
Then after X seconds WDT is causing board to reset. After N boot attempts
we enter recovery mode.

To enter the special mode, one needs to short cut two pads with e.g. screw
driver.
After power up the SPL will execute u-boot in which proper actions will be
taken.
It is worth noting that we do not alter envs (even the BOOT_FROM variable)
and unconditionally go to recovery.

Here we just add a tool for HSDK flashable images preparation
together with extensive documentation for HSDK board.
This will help real-life users to update U-Boot on the board.
HSDK board has preloader that reads SPI flash pages and searches
for a special image header to fetch and load binary.
Add tool, make target (bsp-generate) to generate
update script and u-boot binary image with header for preloader.
Also add script to default environment to apply updates.

The value of PMUFW_INIT_FILE is prefixed with "$(srctree)/", thus
forcing it to be a relative path inside the U-Boot source tree. Since
the PMUFW is a binary file generated outside of U-Boot, the PMUFW
binary must be copied inside the U-Boot source tree before the
build.
This generates a few problems:
* if the source tree is shared among different out-of-tree builds,
they will pollute (and potentially corrupt) each other
* the source tree cannot be read-only
* any buildsystem must add a command to copy the PMUFW binary
* putting an externally-generated binary in the source tree is ugly
as hell
Avoid these problems by accepting an absolute path for
PMUFW_INIT_FILE. This would be as simple as removing the "$(srctree)/"
prefix, but in order to keep backward compatibility we rather use the
shell and readlink to get the absolute path even when starting from a
relative path.
Since 'readlink -f' produces an empty string if the file does not
exist, we also add a check to ensure the file configured in
PMUFW_INIT_FILE exists. Otherwise the build would exit successfully,
but produce a boot.bin without PMUFW as if PMUFW_INIT_FILE were empty.
Tested in the 12 possible combinations of:
- PMUFW_INIT_FILE empty, relative, absolute, non-existing
- building in-tree, in subdir, in other directory
