OK. I set it up that way. Updated patch below.

Sorry, didn't notice you changed it. Fixed now.

Yes, a nice way.

OK, based on your other mail I just left it as PCI && PPC_IBM_CELL_BLADE.
We can change it when another system uses it.

Split the Cell BE support into generic and platform dependent parts.

Creates new config variables PPC_CELL_NATIVE and PPC_IBM_CELL_BLADE.
The existing CONFIG_PPC_CELL is now used to denote the generic
Cell processor support.

Also renames spu_priv1.c to spu_priv1_mmio.c.
