mmc - MMC sub system

Usage:
mmc info - display info of the current MMC device
mmc read addr blk# cnt
mmc write addr blk# cnt
mmc erase blk# cnt
mmc rescan [mode]
mmc part - lists available partition on current mmc device
mmc dev [dev] [part] [mode] - show or set current mmc device [partition] and set mode
  - the required speed mode is passed as the index from the following list
    [MMC_LEGACY, MMC_HS, SD_HS, MMC_HS_52, MMC_DDR_52, UHS_SDR12, UHS_SDR25,
    UHS_SDR50, UHS_DDR50, UHS_SDR104, MMC_HS_200, MMC_HS_400, MMC_HS_400_ES]
mmc list - lists available devices
mmc wp [PART] - power on write protect boot partitions
  arguments:
   PART - [0|1]
       : 0 - first boot partition, 1 - second boot partition
         if not assigned, write protect all boot partitions
mmc hwpartition <USER> <GP> <MODE> - does hardware partitioning
  arguments (sizes in 512-byte blocks):
   USER - <user> <enh> <start> <cnt> <wrrel> <{on|off}>
        : sets user data area attributes
   GP - <{gp1|gp2|gp3|gp4}> <cnt> <enh> <wrrel> <{on|off}>
        : general purpose partition
   MODE - <{check|set|complete}>
        : mode, complete set partitioning completed
  WARNING: Partitioning is a write-once setting once it is set to complete.
  Power cycling is required to initialize partitions after set to complete.
mmc bootbus <dev> <boot_bus_width> <reset_boot_bus_width> <boot_mode>
 - Set the BOOT_BUS_WIDTH field of the specified device
mmc bootpart-resize <dev> <boot part size MB> <RPMB part size MB>
 - Change sizes of boot and RPMB partitions of specified device
mmc partconf <dev> [[varname] | [<boot_ack> <boot_partition> <partition_access>]]
 - Show or change the bits of the PARTITION_CONFIG field of the specified device
   If showing the bits, optionally store the boot_partition field into varname
mmc rst-function <dev> <value>
 - Change the RST_n_FUNCTION field of the specified device
   WARNING: This is a write-once field and 0 / 1 / 2 are the only valid values.
mmc rpmb read addr blk# cnt [address of auth-key] - block size is 256 bytes
mmc rpmb write addr blk# cnt <address of auth-key> - block size is 256 bytes
mmc rpmb key <address of auth-key> - program the RPMB authentication key.
mmc rpmb counter - read the value of the write counter
mmc setdsr <value> - set DSR register value
