on the L333 rev) to distinguish between two BK4 HW revisions.

Add Falcon mode support, which allows the SPL to load and
jump to the Linux kernel directly, without the need of loading
U-Boot proper.
CONFIG_SPL_OS_BOOT=y needs to be passed in the defconfig
in order to use Falcon mode.

We should use a common script to allow booting the U-Boot console as
fallback so we ended using a 'default_boot' and 'base_boot'
environment scripts to accomplish that.

U-Boot binary has grown in such a way that it goes beyond the reserved
area for the environment variables.
Running "saveenv" causes U-Boot to hang because of this overlap.
Fix this problem by increasing the CONFIG_ENV_OFFSET size.
Also, in order to prevent this same problem in the future, use
CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time.
CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare
CONFIG_ENV_OFFSET with its direct value instead.
