[U-Boot-Users] uboot support for USB DFU protocol

I am using the AT91RM9200DK, it has both USB host and device interfaces.

Can I use the USB *device* port to load a binary image (uImage) into my development board?

i.e. does u-boot support the USB DFU (Device Firmware Upgrade) protocol?

I know that the AT91RM9200 has support for USB DFU in its internal boot ROM, but I'd like to use uboot to load the image via image from a file server - similar to the way I would do it with tftp.

If I make a product that has a USB device interface, I'd like to be able to upgrade the firmware via that same USB link.
