f6723794fd TI:omap5: Add rdaddr, use consistent loadaddr values
rdaddr was missing which is a common location for loading ramdisks to.
loadaddr was higher than it needs to be, so use the same value other TI
platforms use.

7406d321cc omap5_common: Re-work mmc boot to try SD and eMMC, correct root device
OMAP5 boards may have both eMMC (on MMC2) and an SD slot (on MMC1).  We
Update the default bootcmd to match what happens on AM335x where we try
SD first, and then eMMC.  In this case however, the hardware layout used
for powering both of these means that in the kernel eMMC shall be found
first as it is powered by a fixed regulator and SD found second as SD is
powered via the palmas which will result in deferred probing.

c3799fceda omap5: Expand CONFIG_SPL_MAX_SIZE and comment upon SRAM_SCRATCH_SPACE_ADDR
After examining both TRMs and doing some experimentation, we can rely on
using the start of the download area for CONFIG_SPL_TEXT_BASE and then
move SRAM_SCRATCH_SPACE_ADDR up, just like am335x.  This is required for
peripheral boot modes such as UART.

a801757480 TI:omap5/dra7xx: Convert to ti_armv7_common.h
Update omap5_common.h to use ti_armv7_common.h, and in turn update
dra7xx_evm.h and omap5_uevm.h slightly.  The biggest changes here are
that IP blocks which exist on the platform, and had clocks enabled,
now have the drivers being built as well.

9552ee3ea9 omap5_uevm.h: Move uEVM-specific choices to omap5_uevm.h
The omap5_uevm platform has eMMC, and it makes sense to say that our
default env storage shall reside there.  Other platforms may not, so
move this choice to the EVM config.  In addition, we should provide some
way to partition the flash for later usage, so take advantage of the GPT
partition table support code and allow that to be setup with some
reasonable defaults.

78fd004107 omap5: Allow use of a plain text env file
For production systems it is better to use script images since
they are protected by checksums and carry valuable information
like name and timestamp. Also, you can't validate the content
passed to env import.

But for development, it is easier to use the env import command and
plain text files instead of script-images.

Since both OMAP5evm/uevm boards are used primarily for development,
we allow U-Boot to load env var from a text file in case that an
boot.scr script-image is not present.

The variable uenvcmd (if existent) will be executed (using run) after
uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
will be started.

Inspired by commit: d70f54808d
(omap4: allow the use of a plain text env file instead boot scripts)

d3501ed584 ARM: OMAP5: Set fdt_high to enable booting with Device tree
While booting with dt blob, if fdt_high is not set to
0xffffffff, the dt blob gets relocated to a high ram address,
which the kernel is not able to use without HIGHMEM.

So set it to 0xffffffff to avoid the issue.
