ESP is Sparc language. MIPS calls the same chip ASC which stands for
Advanced SCSI Controller.

In the various members of the Jazz family if so far seen 53C94 and
FAS216 chips. We might have to deal with other chips also but using esp.c
as base should cover almost all if not all of these cases, so probably
all you need to take care of is the Jazz DMA engine.
