Our original plan for the USB firmware update was to implement USB DFU
(the official USB Device Firmware Upgrade protocol as described in
http://www.usb.org/developers/devclass_docs/usbdfu10.pdf)

I have already implemented USB DFU in gcc-arm, but only specifically for
a AT91SAM7S256 SoC, not for the S3C2410.  My source code for the SAM7
can be found at http://svn.openpcd.org/trunk/firmware/src/dfu/

(if you want to look at the big picture, check out the whole
http://svn.openpcd.org/trunk/firmware/ branch)

If you can try to port or re-implement my SAM7 DFU code to our u-boot on
S3C2410, then this could be the final solution for the end product.

You can find a matching Linux DFU upload/download host program at 
http://people.openpcd.org/laforge/releases/dfu-programmer/0.3.0-hmw4/dfu-programmer-0.3.0-hmw4.tar.bz2

If you have questions about DFU, don't hesitate to contact me.  I did
that other implementation just some two months ago, so the whole
protocol is still very clear in my mind :)
