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

From: Geoff Levand <[email-masked]>
Date: Fri, 28 Apr 2006 14:44:46 -0700

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.
