Looking at the API, I really don't like the mixing of namespaces.
Either it's fw_ or it's firmware_ but not a mix of both.

Also looks like fw_loading_start() would do nothing as the struct is
likely zero initialised, and FW_STATUS_LOADING == 0. Maybe you need an
UNSET enum member?

FW_STATUS_ABORT <- FW_STATUS_ABORTED, to match the adjective suffixes
of the other members. Ditto fw_loading_abort() which doesn't abort
firmware loading but sets the status.

Cheers
