I would love to, but don't have the time at the moment to clean up
the patch. It's very hacky in places, and I can see why it's not
upstream already! I'll probably consider it though next time I have
to merge the patch into future u-boots!

For the archives, the current latest version that fixes this is
http://groups.google.com/group/beagleboard/msg/a565ebfac4c5a43f
(google's search functionality doesn't make it easy to find!)

So that latest patch above also fixed uploads for me (at least into
RAM - haven't tested flash). The problem that I had was that the
pointer to read from (ds->ptr) for uploads was never initialised.
Were there any other bugs with upload?
There's also modifications in my beagle u-boot patch that makes
DFU's RAM partition obey ${loadaddr} for download/upload, and
${filesize} for upload (no more hard-coded 0x200000). I'll try to
get some time to push those patches into the openmoko tree (though I
don't have any devices to test on, so I may call for a patch test
monkey :)
Cheers,
Bernard.
