Thanks for the explanation.  But I think this is overkill for the
sandpoint or true like a sandpoint (Zynx something, Willow, neither of
which are in the kernel tree).  I think we can field the "I wanna hack
on my Sandpoint/8240, but don't see the code under 82xx/!" question. :)

We can certainly investigate just how many distinct boards can be
supported with one image when infos are passed dynamically.  If we can
simplify things enough, maybe we can break the rule of no .[ch] files in
arch/powerpc/platforms since it'll just be 82xx.[ch], 83xx.[ch] and so
on, execept for that damn pmac. ;)
