Few storage technology such is EMMC, UFS, and NVMe support RPMB
hardware partition with common protocol and frame layout.
The RPMB partition cannot be accessed via standard block layer, but
by a set of specific commands: WRITE, READ, GET_WRITE_COUNTER, and
PROGRAM_KEY.
Such a partition provides authenticated and replay protected access,
hence suitable as a secure storage.

A storage device registers its RPMB hardware (emmc) partition or
RPMB W-LUN (ufs) with the RPMB layer providing an implementation for
send_rpmb_req() handler.
Tere is as well simulation platform device. This is handy as an RPMB
key can be programmed only once at storage device lifetime.

The RPMB layer aims to provide in-kernel API for Trusted Execution
Environment (TEE) devices that are capable to securely compute block
frame signature. A TEE driver can claim rpmb interface, for example,
via  class_interface_register ().

A parallel user space API is provided via /dev/rpmbX character
device with a single IOCTL command similar to the one provided by
mmc/ioctl. h
There is a sample tool under tools/rpmb/ directory that exercises
this interface.

Tomas Winkler (8):
  rpmb: add Replay Protected Memory Block (RPMB) subsystem
  char: rpmb: add sysfs-class ABI documentation
  char: rpmb: add device attributes
  char: rpmb: provide user space interface
  char: rpmb: add RPMB simulation device
  tools rpmb: add RPBM access tool
  mmc: block: register rpmb partition with the RPMB subsystem
  scsi: ufs: connect to RPMB subsystem
