Yeah, and with only 16KB of onboard SRAM, I doubt you'd be able to load
U-Boot in as a single image. I don't know if Atmel's host-side DFU app
handles downloads larger than the size of SRAM either. So if not, one
would have to write an app for that on the host as well.

Just out of curiosity, which list would be appropriate then? AT91 Users?
