Hi,
this series add support for board or board+cc runtime DT selection. EEPROM
memory is read and based on that decoded if this is legacy/fru based format
and proper DTB is used. There is a need to have all DTBs 64bit aligned. If
you don't have it you will end up in exception. But one patch in this
series is trying to detect it and panic before you reach it to let you know
what's wrong.
Enforcing mkimage/dtb alignment is done based on CONFIG_PHYS_64BIT and
affects all 64bit systems but it is also not wrong for them to be properly
aligned.
Thanks,
Michal
Changes in v2:
- Update subject and commit message
- Enable 64bit alignment for all - reported by Andre
- Update subject and commit message
- Enable it for all (not just 64bit systems)
- Update if condition for MULTI_DTB
- call fru_capture in non DEBUG mode
- Show detected name as standard message to see what has been chosen
