    B, Ravi authored
    Traditionally the DFU support is available only
    as part 2nd stage boot loader(u-boot) and DFU
    is not supported in SPL.
    The SPL-DFU feature is useful for boards which
    does not have MMC/SD, ethernet boot mechanism
    to boot the board and only has USB inteface.
    This patch add DFU support in SPL with RAM
    memory device support to load and execute u-boot.
    And then leverage full functionality DFU in
    u-boot to flash boot inital binary images to
    factory or bare-metal boards to memory devices
    like SPI, eMMC, MMC/SD card using USB interface.
    This SPL-DFU support can be enabled through
    Menuconfig->Boot Images->Enable SPL-DFU support
