What do you think about including IMMR in the board  info  structure,
and  using  this?  That's  what we're doing for PPCBoot systems (that
don't use/need a special boot loader).

That is a good idea.  I started doing that on the 8260s because you
can't find the IMMR in any special register.  Next, I am going to change
all of the ((immr_t *)IMMR)-> to use a global immr variable.  Then I
am going to remove the IMMR TLB entry, finish the support for large,
wired TLB entries, and have this initialized as part of the m8xx set up.
