Well it's cached, but doesn't have any support for Supervisor mode or
the WISHBONE bus, which means I'll (at the very least) have to write a
bus translator if I want to make it talk to a WISHBONE-compliant device.
The shared instruction/data bus is a nice addition -- will be nice to
get rid of the bus arbitration logic.
The lack of an illegal instruction trap is somewhat concerning, though...
