This is a giant layering violation - the security protocol is not something
up to the LLDD but the core code.

And honestly the idea of defintining a security protocol in the UFS
spec is just as braindead.  If you care about this please take it up
with T10 to get RPMB support into one of the core SCSI specs instead
of a transport.
