Hmm.  The 64M hole was an initial hard code in raminit.c that was just
a small arbitrary hole so we could access I/O devices until everything is
setup properly.

mmio_basek should be the lowest address at which we have devices.  So cpufixup.c
should be doing the right thing.

Although I have a few pieces to update.

Ok.  It really depends on how your bus is enumerated.
