It was my first implementation, but in that case you have to manage a
session, switching on RPMB partition at the begining of the IOCTL and
restore previous partition at the end. (because RPMB partition doesn't
support all commands).
Having a look to how mmc driver manages partition selection, I saw
that mmc_blk_issue_rq for instance calls mmc_blk_part_switch in the
beginning to be sure it's on the right partition, but never restores
The proposal is to use same way and to make it compliant with Boot and
GP partitions if there are any special commands supported by them.
