RE: kernel startup

Since I have set IIP to 1, reset vector is at 0xfff00100.  IMMR is
0x00f00000. So, putting RAM at address 0x0 allows only 15MB of RAM
at address 0x0 (ISA style).=20

As memory and internal processor registers would conflict, I would have
a memory hole.  Hence, the logical choice of putting RAM at a different
location. So, if MMU allows shadowing (which I have not read), it could
solve my problem.

I'm not that familiar with 8xx, but can't you move IMMR?
