[patch 2/4] cell: split out platform code
Geoff Levand

Sat Apr 29 07:44:46 EST 2006
Split the Cell BPA support into generic and platform
dependant parts.
Creates a new config variable CONFIG_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.
