When building with khadas-vim3_android_defconfig, we can see that CMD_BCB is no
longer part of that build:
$ grep CMD_BCB .config
<empty>
However, if we look at include/configs/meson64_android.h, we can see
that the "bcb" command is not only used for checking the _slot suffix.
It's also used for checking the bootloader reason. For example, in
BOOTENV_DEV_FASTBOOT, we call:
"if bcb test command = bootonce-bootloader; then " \
Since CMD_BCB is no longer part of the .config (due to this dependency),
the boot script now shows errors:
"""

"""
I know we should not be using a boot script, nor non A/B configs but
it's a bummer that this series breaks an upstream
defconfig (khadas-vim3_android_defconfig)
My recommendation:
Make BCB_CMD_AB_SELECT implementation dependant on ANDROID_AB.
This way, users can use CMD_BCB with and without ANDROID_AB being enabled.
We could do:
When ANDROID_AB=y, implement bcb ab_select subcommand
When ANDROID_AB=n, command is not accessible.
I'll send you a diff shortly for this.
