cmd: bcb: introduce 'ab_dump' command to print BCB block content
It's really helpful to have the ability to dump BCB block for debugging
A/B logic on the board supported this partition schema.
Command 'bcb ab_dump' prints all fields of bootloader_control struct
including slot_metadata for all presented slots.
Output example:
=====
> board# bcb ab_dump ubi 0#misc
> Read 512 bytes from volume misc to 000000000bf07580
> Read 512 bytes from volume misc to 000000000bf42f40
> Bootloader Control: [misc]
> Active Slot: _a
> Magic Number: 0x42414342
> Version: 1
> Number of Slots: 2
> Recovery Tries Remaining: 0
> CRC: 0x2c8b50bc (Valid)
>
> Slot[0] Metadata:
> - Priority: 15
> - Tries Remaining: 0
> - Successful Boot: 1
> - Verity Corrupted: 0
>
> Slot[1] Metadata:
> - Priority: 14
> - Tries Remaining: 7
> - Successful Boot: 0
> - Verity Corrupted: 0
====
The ab_dump command allows you to display ABC data directly on the
U-Boot console. During an A/B test execution, this test verifies the
accuracy of each field within the ABC data.
