Hi Michal,

On systems with FWU enabled but without the required DT changes the FWU
metadata device is not found and fwu_boottime_checks() returns an error.
Being an initcall, that non-zero return aborts the boot flow
Return 0 instead so the boot continues. The preceding log_err() still
tells the user that the FWU device could not be found.
Won't that affect the board later on? E.g When you do capsule updates,
updating the metadata will fail
Do you mean on systems without mdata?
Yes. if the config is enabled it will make the capsule update code
searching and updating metadata.
fwu mdata backend is not enabled hence not used. fwu just returns 0 in dump.
Updating metadata will never call any backend.
Some logs below.
Thanks,
Michal
