Hmm, since there is not much documentation available for SpursEngine, it's
rather hard to tell what needs to be done for it.
If we think that it will hit the kernel anytime soon, we could use fs/spufs
instead of arch/powerpc/spufs right away. Interestingly, this is where it was
initially, but got moved to arch/powerpc/platforms/cell/spufs after a lot
of discussion ;-).

There is very little code in platforms/cell that can not be generic, so I think
it's not worth splitting it. The only IBM blade specific files are
cbe_cpufreq_pmi.c and parts of setup.c and pervasive.c. Everything else could
be shared by about any generic implementation without a hypervisor.
