How do we know if the board is using EFI bootmgr? My understanding was
that this was a way to find out?
The boot manager must always run.
The check for the BootOrder variable introduced in commit f2bfa0cb1794
is a bug.
The boot manager handles in sequence:
* Try to boot as indicated by BootNext.
* Try to boot as indicated by BootOrder.
* Try to boot default path for available media.
This will add Boot#### entries and update BootOrder.
Best regards
Heinrich
