The patch series include changes:
- move ab_select_slot() documentation to @ notation
- move ab_select command to bcb subcommands
- introduce the ab_dump command to print the content of the BCB
block; it's useful for debugging A/B logic on supported boards
- fix the slot suffix format in the ABC block to align with official
Android BCB specifications
- add a test for the ab_dump command to verify the accuracy of each
field within the ABC data displayed, it's also useful for testing
slot_suffix problem code paths
Changes v3 since v2 at [2]:
- return "Legend" block for bcb command
- additionally, verify the CONFIG_ANDROID_AB configuration alongside
CONFIG_CMD_BCB to ensure that the A/B scheme is used for the
designated board.
Changes v2 since v1 at [1]:
- move ab_select_slot() documentation to @ notation
- move ab_select command to bcb subcommands per Simon and Mattijs
suggestions
- redesign ab_dump as bcb subcommand
- use spaces instead of tabs in the ab_dump command output
- print hex values in the lowercase
- add RvB tags
