Now that I think a little more, this concern is not only unconfirmed,
it is rather absurd. The firmware would never write in parts of the

UEFI understands the EFI system filesystem so it can "safely" write new
files there.
The danger then is that a write via mdadm corrupts the filesystem. I'm
not sure if mdadm will detect the inconsistent data or assume both
sources are the same.
Hardware raid that the bios cannot subvert is obviously one solution.
