f5996449e3 [POWERPC] cell: Move SPU affinity init to spu_management_of_ops
This patch moves affinity initialization code from spu_base.c to a
new spu_management_of_ops function (init_affinity), which is empty
in the case of PS3. This fixes a linking problem that was happening
when compiling for PS3.
Also, some small code style changes were made.

c9868fe0e0 [POWERPC] Celleb: consolidate spu management ops
Spu management ops in arch/platforms/cell/spu_priv1_mmio.h can be used
commonly in of based platform. This patch separates spu management ops
from native cell code and uses on celleb platform.

e28b003136 [POWERPC] cell: abstract spu management routines
This adds a platform specific spu management abstraction and the coresponding
routines to support the IBM Cell Blade.  It also removes the hypervisor only
resources that were included in struct spu.

Three new platform specific routines are introduced, spu_enumerate_spus(),
spu_create_spu() and spu_destroy_spu().  The underlying design uses a new
type, struct spu_management_ops, to hold function pointers that the platform
setup code is expected to initialize to instances appropriate to that platform.

For the IBM Cell Blade support, I put the hypervisor only resources that were
in struct spu into a platform specific data structure struct spu_pdata.

24f43b33f7 [POWERPC] spufs: wrap mfc sdr access
SPRN_SDR1 and the SPE's MFC SDR are hypervisor resources and
are not accessible from a logical partition.  This change adds an
access wrapper.

When running on bare H/W, the spufs needs to only set the SPE's MFC SDR
to the value of the PPE's SPRN_SDR1 once at SPE initialization, so this
change renames mfc_sdr_set() to mfc_sdr_setup() and moves the
access of SPRN_SDR1 into the mmio wrapper.  It also removes the now
unneeded member mfc_sdr_RW from struct spu_priv1_collapsed.

a91942ae7e [POWERPC] spufs: fix spu irq affinity setting
This changes the hypervisor abstraction of setting cpu affinity to a
higher level to avoid platform dependent interrupt controller
routines.  I replaced spu_priv1_ops:spu_int_route_set() with a
new routine spu_priv1_ops:spu_cpu_affinity_set().

As a by-product, this change eliminated what looked like an
existing bug in the set affinity code where spu_int_route_set()
mistakenly called int_stat_get().

540270d82d [POWERPC] spufs: further abstract priv1 register access
To support muti-platform binaries the spu hypervisor accessor
routines must have runtime binding.

I removed the existing statically linked routines in spu.h
and spu_priv1_mmio.c and created new accessor routines in spu_priv1.h
that operate indirectly through an ops struct spu_priv1_ops.
spu_priv1_mmio.c contains the instance of the accessor routines
for running on raw hardware.
