Are any applications using the RPMB code from ufs-utils? It seems to me 
that the ufs-utils code doe not handle SCSI unit attentions correctly. 
If a POWER ON unit attention is received as reply to a SECURITY PROTOCOL 
OUT transaction, the write counter should be reread instead of retrying 
the SECURITY PROTOCOL OUT command with the same write counter.

Regarding adding a UFS RPMB driver: that seems useful to me since 
multiple applications make use of the UFS RPMB functionality. My 
understanding is that currently storageproxyd multiplexes UFS RPMB 
accesses in Android.

Thanks,

Bart.
