new CPU

Jan. 1, 2008

I'm interested in an implementation of openfirmware on an arm9 cpu. I see that there are several implementations available. Where's the best place to start? SmartFirmware seems to be the closest as there's support for an arm7 board (edb7312) but it looks a little out of date. Any suggestions? Regards, Jose
