3c8464a9b1 powerpc: Delete old PrPMC 280/2800 support
This processor/memory module was mostly used on ATCA blades and
before that, on cPCI blades.  It wasn't really user friendly, with
custom non u-boot bootloaders (powerboot/motload) and no real way
to recover corrupted boot flash (which was a common problem).

As such, it had its day back before the big ppc --> powerpc move
to device trees, and that was largely through commercial BSPs that
started to dry up around 2007.

Systems using one were largely in a "deploy and sustain" mode,
so interest in upgrading to new kernels in the field was nil.
Also, requiring 50A, 48V power supplies and a 2'x2'x2' ATCA
chassis largely rules out any hobbyist/enthusiast interest.

The point of all this, is that we might as well delete the in
kernel files relating to this platform.  No point in continuing
to build it via walking the defconfigs or via linux-next testing.

be2019816e powerpc/embedded6xx: Add support for Motorola/Emerson MVME5100
Add support for the Motorola/Emerson MVME5100 Single Board Computer.

The MVME5100 is a 6U form factor VME64 computer with:

	- A single MPC7410 or MPC750 CPU
	- A HAWK Processor Host Bridge (CPU to PCI) and
	  MultiProcessor Interrupt Controller (MPIC)
	- Up to 500Mb of onboard memory
	- A M48T37 Real Time Clock (RTC) and Non-Volatile Memory chip
	- Two 16550 compatible UARTS
	- Two Intel E100 Fast Ethernets
	- Two PCI Mezzanine Card (PMC) Slots
	- PPCBug Firmware

The HAWK PHB/MPIC is compatible with the MPC10x devices.

There is no onboard disk support. This is usually provided by installing a PMC
in first PMC slot.

This patch revives the board support, it was present in early 2.6
series kernels. The board support in those days was by Matt Porter of
MontaVista Software.

CSC Australia has around 31 of these boards in service. The kernel in use
for the boards is based on 2.6.31. The boards are operated without disks
from a file server.

This patch is based on linux-3.13-rc2 and has been boot tested.

Only boards with 512 Mb of memory are known to work.

  ntpd[2713]: unhandled signal 4 at 0fd5b448 nip 0fd5b448 lr 0fd5b424 code 30001

The root cause is that the float point instruction 'fsqrt' is used.

does seem a gcc bug, I would like to enable the math emulation

Pull powerpc updates from Benjamin Herrenschmidt:
 "So from the depth of frozen Minnesota, here's the powerpc pull request
  for 3.9.  It has a few interesting highlights, in addition to the
  usual bunch of bug fixes, minor updates, embedded device tree updates
  and new boards:

   - Hand tuned asm implementation of SHA1 (by Paulus & Michael
     Ellerman)

   - Support for Doorbell interrupts on Power8 (kind of fast
     thread-thread IPIs) by Ian Munsie

   - Long overdue cleanup of the way we handle relocation of our open
     firmware trampoline (prom_init.c) on 64-bit by Anton Blanchard

   - Support for saving/restoring & context switching the PPR (Processor
     Priority Register) on server processors that support it.  This
     allows the kernel to preserve thread priorities established by
     userspace.  By Haren Myneni.

   - DAWR (new watchpoint facility) support on Power8 by Michael Neuling

   - Ability to change the DSCR (Data Stream Control Register) which
     controls cache prefetching on a running process via ptrace by
     Alexey Kardashevskiy

   - Support for context switching the TAR register on Power8 (new
     branch target register meant to be used by some new specific
     userspace perf event interrupt facility which is yet to be enabled)
     by Ian Munsie.

   - Improve preservation of the CFAR register (which captures the
     origin of a branch) on various exception conditions by Paulus.

   - Move the Bestcomm DMA driver from arch powerpc to drivers/dma where
     it belongs by Philippe De Muyter

   - Support for Transactional Memory on Power8 by Michael Neuling
     (based on original work by Matt Evans).  For those curious about
     the feature, the patch contains a pretty good description."

e0e8398e3a powerpc/85xx: Board support for ppa8548
Initial board support for the Prodrive PPA8548 AMC module. Board
is an MPC8548 AMC platform used in RapidIO systems. This module is
also used to test/work on mainline linux RapidIO software.

PPA8548 overview:
- 1.3 GHz Freescale PowerQUICC III MPC8548 processor
- 1 GB DDR2 @ 266 MHz
- 8 MB NOR flash
- Serial RapidIO 1.2
- 1 x 10/100/1000 BASE-T front ethernet
- 1 x 1000 BASE-BX ethernet on AMC connector

d5bc813f40 powerpc/85xx: enable MTD options in sbc8548 defconfig
This board has soldered on flash, and a SODIMM flash module.
Both can be used for booting, via switching JP12 and SW2.8
and using the sbc8548-altflash.dts when booting from SODIMM.

Here we enable MTD in kernel so that we can see the bootloader
(and other flash sectors) from linux.

Normal configuration:

 mtd0: 007a0000 00020000 "space"
 mtd1: 00060000 00020000 "bootloader"

Note that in the latter, the larger SODIMM device appears 1st,
as mtd0 and mtd1, as indicated in the sizes, and in the date
of the u-boot image.

The kernel configuration is the same in both cases; only the dtb
needs to be changed in accordance with the JP12/SW2.8 settings.

34f364fef4 powerpc/fsl: Remove CONFIG_IRQ_ALL_CPUS from mpc85xx/mpc86xx defconfig
While this should be harmless now that distribute_irqs
obeys MPIC_SINGLE_DEST_CPU, there's no reason to enable this
on mpc85xx/mpc86xx since MPIC_SINGLE_DEST_CPU will always be set.
