     Thanks for contribution. I'm trying to make platform-independent
part of mips/ tree and userland stable and once it's done more time
will be available for adding new platforms (I hope it will be soon
enough) :)
     Meanwhile I'd appreciate if you test attached patch for busdma
with your hardware. This implementation has been shamelessly ripped
from arm code tree and should handle alignment/boundaries limitations
properly. If possible, test with several DMA-enabled devices working
simultaneously. Thanks.
