Environment variable mcinitcmd is defined to initiate MC and DPL deployment from the location where it is stored(NOR, NAND, SD, SATA, USB)during u-boot booting.If this variable is not defined then macro MC_BOOT_ENV_VAR will be null and MC will not be booted and DPL will not be applied during U-boot booting.
