Re: [U-Boot] [PATCH v3] env: ti: boot: Handle reboot reason from BCB

In case of Android boot, reboot reason can be written into BCB (usually it's an area in 'misc' partition). U-Boot then can obtain that reboot reason from BCB and handle it accordingly to achieve correct Android boot flow, like it was suggested in [1]:

• if it's empty: perform normal Android boot from eMMC
• if it contains "bootonce-bootloader": get into fastboot mode
• if it contains "boot-recovery": perform recovery boot

The latter is not implemented yet, as it depends on some features that are not implemented on TI platforms yet (in AOSP and in U-Boot).
