I've done some work with bitswap (and fliptable) in a separate .S file (easier that way, IMO), and I have something that builds, but crashes at some unkown location (not in bitswap). Don't know where yet, but I guess somewhere in mpeg.c. It's difficult to pinpoint with next to no debug facilities...
From what I've gathered, I get data in r4 and length in r5. Do any registers need to be saved (doesn't work if I save or not though)?
