00caae6d47 env: Rename getenv/_f() to env_get()
We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

c62db35d52 arm: Add explicit include of <asm/mach-types.h>
Rather than relying on common.h to provide this include, which is going
away at some point, include it explicitly in each file.

d5abcf94c7 ti: boot: Register the MMC controllers in SPL in the same way as in u-boot
To keep a consistent MMC device mapping in SPL and in u-boot, let's
register the MMC controllers the same way in u-boot and in the SPL.
In terms of boot time, it doesn't hurt to register more controllers than
needed because the MMC device is initialized only prior being accessed for
the first time.
Having the same device mapping in SPL and u-boot allows us to use the
environment in SPL whatever the MMC boot device.

523849a088 kc1: Proper reboot mode and boot reason validation
With the previous implementation, rebooting without registering a recognized
reboot mode would end up with U-Boot checking for a valid power-on reason, which
might result in the device turning off (e.g. with no USB cable attached and no
buttons pressed).

Since this approach is not viable (breaks reboot in most cases), the validity of
the reboot reason is checked (in turn, by checking that a warm reset happened,
as there is no magic) to detect a reboot and the 'o' char is recognized to
indicate that power-off is required. Still, that might be overridden by the
detection of usual power-on reasons, on purpose.

dcac8843a8 kc1: Clear reboot mode garbage on cold reset
Reboot mode garbage is found on cold reset and might be seen as valid on the
next warm reset, thus it has to be cleared on cold reset.

ee85a41525 kc1: Power off when the power on reason is not a valid one
Some power on reasons are not desirable (e.g. too short press on the power
button), battery plug. Thus, power off the device when one of those occurs.

7c0a4b7955 kc1: OMAP4 reboot mode support
This adds support for the omap4 reboot mode mechanism and exports the reboot
mode via an environment variable, that is used in the boot command to make it
possible to boot from the recovery partition or fastboot.

ae51b5709e Amazon Kindle Fire (first generation) codename kc1 support
The Amazon Kindle Fire (first generation) codename kc1 is a tablet that was
released by Amazon back in 2011.

It is using an OMAP4430 SoC GP version, which allows running U-Boot and the
U-Boot SPL from the ground up.
