The mmc-utils was modified to invoke eMMC5.0 Field Firmware Update (FFU)
process in mmc driver
New command was add: "do_emmc50_ffu".
This patch depends on patch mmc: Support-FFU-for-eMMC-v5.0 Committed by Avi
Shchislowski <avi.shchislow...@sandisk.com>
FFU will be done in two steps. Two new IOCTL codes will be sent to the driver
in order to operate FFU code:
1. FFU_DWONLOAD_OP (sent in ffu_download_image() function)
2. FFU_INSTALL_OP (sent in ffu_install() function)
