[RFC PATCH 0/5] RPMB internal and user-space API + WIP virtio-rpmb frontend

From: Avri Altman

The mmc driver has some hooks to support rpmb access, but access is
mainly facilitated from user space, e.g. mmc-utils.

The ufs driver has no concept of rpmb access - it is facilitated via
user space, e.g. ufs-utils and similar.

Both for ufs and mmc, rpmb access is defined in their applicable jedec
specs. This is the case for few years now - AFAIK No new rpmb-related
stuff is expected to be introduced in the near future.

What problems, as far as mmc and ufs, are you trying to solve by this new subsystem?

Thanks,
Avri
