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.
Changes in V5: - move changelog to the right place for each patches - add empty changelog for patches with no change - change lib/Makefile for adding sha256 when CONFIG_SUPPORT_EMMC_RPMB is defined
Changes in V4: - use subcommand tables for 'mmc' command and 'mmc rpmb' subcommand. - add 'mmc info' subcommand, which is the same as mmcinfo. mmcinfo is kept for compatibility. - add changelog in commit comments.
Changes in V3: - add entries in README for configuration options related to eMMC. - new patch for adding the 'confirm_yesno' function as suggested by W.Denk - improved test for existence of RPMB partition. - fix of coding issues.
Changes in V2: - use ALLOC_CACHE_ALIGN_BUFFER in rpmb.c instead of a static buffer for the RPMB frames.
