[U-Boot] [PATCH v3 0/7] dfu:usb: DFU support via USB Download gadget

[Lukasz Majewski]

Those patches add support for composite USB download gadget.
This gadget (at least for now) is equipped with DFU download function.

A separate DFU back-end and front-end have been added.
Back-end is placed at ./drivers/dfu directory. The front-end is implemented
as USB function.

The back-end is written in a generic manner with storage device specific
code separated (eMMC).

DFU specification can be found at:
http://wiki.openmoko.org/wiki/USB_DFU_-_The_USB_Device_Firmware_Upgrade_standard

Example usage:

u-boot side: dfu mmc 0
PC: dfu-util -U IMAGE.bin -a uImage (for upload)
    dfu-util -D uImage -a uImage (download)

To list the alt settings:
        dfu mmc 0 list

Test HW:
        Exynos4210 Trats board
