The omap5-uevm is the reference board name for OMAP5 soc
based platform. So rename it accordingly.

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.

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: d70f54808dfa83b574e1239c3eccbcf3317343e1
(omap4: allow the use of a plain text env file instead boot scripts)

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.

I missed this part before, sorry. What we do on am335x_evm to allow
for easier overrides is:
- bootcmd runs findfdt (since we'll need it in all cases).
- Enable CONFIG_CMD_FS_GENERIC
- Add a 'loadfdt' command that can be called out ala loaduimage
- Use 'load' in loadfdt/loaduimage so that we don't care what the
underlying filesystem type is.
- Use bootdir to help with overrides as well:
loaduimage=load mmc ${bootpart} ${loadaddr} ${bootdir}/${bootfile}
loadfdt=load mmc ${bootpart} ${fdtaddr} ${bootdir}/${fdtfile}
So that we can easily grab from the first partition (FAT) or another
partition (ext3/4/etc).

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.
