I think that's a more fundamental change to CPM early debug than I can
handle right now.

Is IMMRBASE on your board at some address that has a low likelihood of
conflicting when treated as a kernel effective address?

It's at 0x0f000000, is seems ok, but then I'm not sure I fully
understand kernel effective addresses.

That overlaps userspace -- is the BAT cleared before userspace starts?

If you don't want to do the fixmap stuff, might want to at least just 
leave it at the current arbitrary effective address, which hasn't seemed 
to cause much trouble so far.

But fixmap is the right way to do it.
