I'll be happy to do so.
I too am working on the SD/MMC card stack. I have one boot loader for
the AT91RM9200 working, and have been hacking on a quick and dirty
driver for that part, but it needs to have the transport layer
separated out from the MMC/SD protocol goo. Maybe we can work
together to produce something that fits both our needs?
