47c6ea076e ARM: OMAP: Add arch_cpu_init function
The boot parameters passed from SPL to UBOOT
must be saved as a part of uboot's gd data
as early as possible, before we will inadvertently
overwrite it. So adding a arch_cpu_init for the required
Socs to save it.

85b7ac4588 omap5_common: Add optargs variable for kernel command line args
Add 'optargs' variable to be set to additional kernel arguments, similar
to omap3*/am3* usage.

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.

aaed0a23c9 ARM: OMAP4/5: Make bootz as the default boot command
So with OMAP added to multi platform kernel,
the uImage no more contains a valid load address.
With the uboot already supporting zImage,
change the default boot command to bootz
instead.

143070df8e ARM: OMAP4/5: Change the default boot command to work with device tree
Now with kernel moving to all device tree, the default
boot command is changed to pass the device tree blob.
Also, adding the findfdt command to get the dt-blob
based on the board.

Thanks to Tom Rini <trini@ti.com> for suggesting this.

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.
