You can share physical memory as long as each processor is dedicated
to separate regions.  However, Linux on power expects memory to be
based at 0.  Therefore you need to tweak the memory design so that the
second processor sees a different area of the ram based at zero.

You can even setup a shared memory region between the two processors,
but you that region should be cache-inhibited.
