commit a969e76a (powerpc: Correct USB
support for GE Fanuc SBC610) introduced a fixup for NEC usb controllers.
This fixup should only run on GEF SBC610 boards.

Fixes Fedora bug #486511.

Basic support for the GPIO available on the SBC610 VPX Single Board Computer
from GE Fanuc (PowerPC MPC8641D).

This patch adds basic support for the GPIO in the devices I/O FPGA, the GPIO
functionality is exposed through the AFIX pins on the backplane, unless used
by an AFIX card.

This code currently does not support switching between totem-pole and
open-drain outputs (when used as outputs, GPIOs default to totem-pole).
The interrupt capabilites of the GPIO lines is also not currently supported.

The Freescale implementation of MPIC only allows a single CPU destination
for non-IPI interrupts.  We add a flag to the mpic_init to distinquish
these variants of MPIC.  We pull in the irq_choose_cpu from sparc64 to
select a single CPU as the destination of the interrupt.

This is to deal with the fact that the default smp affinity was
changed by commit 18404756 ("genirq:
Expose default irq affinity mask (take 3)") to be all CPUs.

Most of the platforms were printing the size of the memory
in their show_cpuinfo implementations. This moves that to
the common show_cpuinfo, so that all 32-bit platforms will
now print the size of memory.  I also update the code
to deal with the fact that total_memory is now a phys_addr_t.

- Get rid of uses_fsl_uli_m1575, it does not scale for all cases.
  Instead, let's explicitly use machine_is() for each fixup.
- Factor out MPC8610HPCD quirks to fsl_uli1575, and protect them with
  machine_is(). One step closer to multiplatform kernels.
- Actually use fsl_uli1575 on MPC8610HPCD, so RTC quirk will be applied.
- RTC quirk applies to all boards though, so no machine_is() checks.

Choosing PCI or not at config time is allowed on some
platforms via an if expression in arch/powerpc/Kconfig.
To add a new platform with PCI support selectable at
config time, you must change the if expression.  This
patch makes this easier by changing:
    bool "PCI support" if <long expression>
to
    bool "PCI support" if PPC_PCI_CHOICE
and adding select PPC_PCI_CHOICE to all the config nodes that
were previously in the PCI if expression.

Platforms with unconditional PCI support continue to
just select PCI in their config nodes.

Currently create_branch() creates a branch instruction for you, and
patches it into the call site.  In some circumstances it would be nice
to be able to create the instruction and patch it later, and also some
code might want to check for errors in the branch creation before
doing the patching.  A future commit will change create_branch() to
check for errors.

For callers that don't care, replace create_branch() with
patch_branch(), which just creates the branch and patches it directly.

While we're touching all the callers, change to using unsigned int *,
as this seems to match usage better.  That allows (and requires) us to
remove the volatile in the definition of vector in powermac/smp.c and
mpc86xx_smp.c, that's correct because now that we're passing vector as
an unsigned int * the compiler knows that it's value might change
across the patch_branch() call.

they didn't fit anywhere else. I'd like to clean them up a little and add
some more, so first move them into a dedicated C file - they don't need to

The interrupt routing in the device trees for the ULI M1575 was
inproperly using the interrupt line field as pci function.  Fixed
up the device tree's to actual conform for to specification and
changed the interrupt mapping code so it just uses a static mapping
setup as follows:

PIRQA - IRQ9
PIRQB - IRQ10
PIRQC - IRQ11
PIRQD - IRQ12
USB 1.1 OCHI (1c.0) - IRQ12
USB 1.1 OCHI (1c.1) - IRQ9
USB 1.1 OCHI (1c.2) - IRQ10
USB 1.1 ECHI (1c.3) - IRQ11
LAN (1b.0) - IRQ6
AC97 (1d.0) - IRQ6
Modem (1d.1) - IRQ6
HD Audio (1d.2) - IRQ6
SATA (1f.1) - IRQ5
SMB (1e.1) - IRQ7
PMU (1e.2) - IRQ7
PATA (1f.0) - IRQ14/15

Took the oppurtunity to refactor the code into a single file so we
don't have to duplicate these fixes on the two current boards in the
tree and several forth coming boards that will also need the code.

Fixed RTC support that requires a dummy memory read on the P2P bridge
to unlock the RTC and setup the default of the RTC alarm registers to
match with a basic x86 style CMOS RTC.

Moved code that poked ISA registers to a FIXUP_FINAL quirk to ensure
the PCI IO space has been setup properly before we start poking ISA
registers at random locations.

On the 85xx/86xx PCIe controllers if there is no device connected to the

correct and so we just mimic the resources from the upstream pci_bus.
