[U-Boot] [PATCH v4 0/4] Add 'bcb' command to read/modify/write Android BCB

[Eugeniu Rosca]

The first patch does the necessary fixing and polishing of
include/android_bootloader_message.h and is a hard prerequisite
for this series.

The second patch performs the implementation of the 'bcb' command.
The third patch relocates the Android README to doc/android.
The fourth patch describes the motivation and foreseeable use-cases
behind the 'bcb' command in the newly created doc/android/bcb.txt.

v4:
 - [Simon Glass] Non-functional refinements in cmd/bcb.c
 - [Sam Protsenko] Fix stale references of Android docs
 - Place detailed stats in each patch.
