How about adding the  "sim" interface & target?

The idea is to be able to run regression tests in software
only.

Another piece to the puzzle is that GDB has a "target sim"
for just about any CPU architecture.

Outline of crazy idea follows:

- add a "simarm" interface. This simarm interface implements
a JTAG slave that OpenOCD talks to.
- This JTAG slave controls a GDB running "target sim"

For regression testing purposes, it would probably suffice to implement
this for ARM, but it should work for MIPS too...

Lots of blanks & questions in this idea. The biggest of which is
who would pick up the gauntlet ;-)
