This serie of patches adds some functions and a sub-command of 'mmc' for programming the authentication key and for reading and writing the RPMB partition of an eMMC according to the JEDEC standard No. 64-A441
The sub-command rpmb is enabled by the flag CONFIG_SUPPORT_EMMC_RPMB defined in the board configuration file. It has been tested on a SabreSDP iMX6 board.
