Actually, it can be anywhere between 0xc8000 and 0xd4000, maybe even
higher than that, I can't remember.  The MMU isn't really involved.  the
SC4x0 generates a bunch of chipselects whose active address windows can be
set using addressed registers.  The PCMCIA system is involved on SC400,
and the vestiges of it are involved on SC410.  Interestingly, there's also
a chip called SC405, but I can't get AMD to admit that it exists...
