+ help
+ Currently the SPL does not have capability to load the
+ binaries or boot images to boot devices like ram,eMMC,SPI,etc.
+ This feature enables the DFU (Device Firmware Upgarde) in SPL with
+ RAM memory device support. The ROM code will load and execute
+ the SPL built with dfu. The user can load binaries (u-boot/kernel) to
+ selected device partition from host-pc using dfu-utils.
+ This feature will be useful to flash the binaries to factory
+ or bare-metal boards using USB interface.
