I'm running into some difficulties converting the mipsco asc driver-glue...
It makes extensive use of the Rambo ASIC's DMA FIFO, but to my knowledge
the R4030 ASIC has no such FIFO, just the address of a buffer.
Can anyone lend any guidance on how I should deal with this?  I don't have
any R4030 docs, I'm just working with what I can piece together from header
files and current code...

Thanks,
