I think it should probably be a separate processor family.  If
there are parts that you can bring in from m68k, then perhaps find
a way to use them from a common location, but if you need to riddle
the code with ifdefs or do some kind of Macro Magic to share
significant amounts of code, then I think it's a net loss in
readability and maintainability.

I don't think we're seeing any new m68k hardware/processors/etc.,
and I suspect that as coldfire evolves it will accrete its own
ifdefs.  Is there sufficient reason to carry the m68k baggage,
too?

Those are my thoughts, anyway.
