Add commands to get and set write protect modes for the specified areas of the user partition. The ability to set permanent write protect is #ifdef'd with "DANGEROUS_COMMANDS_ENABLED" because it has the ability to make the eMMC device and possibly the system permanently unusable.

Adding support for field firmware update over multiple command ioctl. As multiple command ioctl is supported only from kernel 4.4, this patch should be used against kernel 4.4 and above. Known issues: - There is no support for Multiple Block write commands (CMD25) in existing IOCTL implementation - In case MODE_OPERATION_CODES field is not supported by the device manual reset of the device/platform is required. The reset issue discussed in another email thread - " [RFC 0/6] mmc: Field Firmware Update" Signed-off-by: Yaniv Agman <yaniv.agman@sandisk.com> Signed-off-by: Avi Shchislowski <avi.shchislowski@sandisk.com> Signed-off-by: Chris Ball <chris@printf.net>

The lsmmc tools contains an extensive parser of the CID, CSD, SCR registers from userspace. The utility works as-is and uses sysfs to read the register values. The original code is created by Sebastian Rasmussen and still lives in an attachment in the mail archive of linux-mmc. It need to be merged into mmc-utils repository, which is convenient for testing MMC device from userspace. Change since v3: - Remove the unused EXT_CSD parser in lsmmc.c file.

3rd party HMAC SHA256 implementation has been added to the driver, and since driver common code (mmc_cmds.c) includes calling to routines and data structures that reside in these 3rd party files (under 3rdparty\hmac_sha) these files should be compiled as well in Android.mk makefile.

mmc rpmb write-key <rpmb device> <key file> Program authentication key which is 32 bytes length and stored in the specified file. Also you can specify '-' instead of key file path and utility will read the key from stdin. BEWARE: key can be programmed only once! Example: $ echo -n AAAABBBBCCCCDDDDEEEEFFFFGGGGHHHH | mmc rpmb write-key /dev/mmcblk0rpmb - mmc rpmb read-counter <rpmb device> Counter value for the <rpmb device> will be read to stdout. mmc rpmb read-block <rpmb device> <address> <blocks count> <output file> [key file] Blocks of 256 bytes will be read from <rpmb device> to output file or stdout if '-' is specified instead of regular path. If key is specified - read data will be verified. Instead of regular path you can specify '-' and key will be read from stdin. Example: $ echo -n AAAABBBBCCCCDDDDEEEEFFFFGGGGHHHH | \ mmc rpmb read-block /dev/mmcblk0rpmb 0x02 2 /tmp/block - or read the block without verification $ mmc rpmb read-block /dev/mmcblk0rpmb 0x02 2 /tmp/block mmc rpmb write-block <rpmb device> <address> <256 byte data file> <key file> Block of 256 bytes will be written from data file to <rpmb device>.

Extract a function which sets the OTP PARTITION_SETTING_COMPLETE bit; once this bit is set there are many other parameters in EXT_CSD which can no longer be set.
