This patch adds the vector move instructions:

  - xvnabsdp - Vector Negative Absolute Value Double-Precision
  - xvnegdp - Vector Negate Double-Precision
  - xvcpsgndp - Vector Copy Sign Double-Precision
  - xvabssp - Vector Absolute Value Single-Precision
  - xvnabssp - Vector Negative Absolute Value Single-Precision
  - xvnegsp - Vector Negate Single-Precision
  - xvcpsgnsp - Vector Copy Sign Single-Precision

V3: Per Paolo Bonzini's suggestion, used a temporary for the
sign mask and andc.

This patch adds the VSX scalar move instructions:

  - xsabsdp (Scalar Absolute Value Double-Precision)
  - xsnabspd (Scalar Negative Absolute Value Double-Precision)
  - xsnegdp (Scalar Negate Double-Precision)
  - xscpsgndp (Scalar Copy Sign Double-Precision)

A common generator macro (VSX_SCALAR_MOVE) is added since these
instructions vary only slightly from each other.

Macros to support VSX XX2 and XX3 form opcodes are also added.
These macros handle the overloading of "opcode 2" space (instruction
bits 26:30) caused by AX and BX bits (29 and 30, respectively).

V3: Per feedback from Paolo Bonzini, moved the sign mask into a
temporary and used andc.

We use the rom infrastructure to write firmware and/or initial kernel
blobs into guest address space. So we're basically emulating the cache
off phase on very early system bootup.

That phase is usually responsible for clearing the instruction cache for
anything it writes into cachable memory, to ensure that after reboot we
don't happen to execute stale bits from the instruction cache.

So we need to invalidate the icache every time we write a rom into guest
address space. We do not need to do this for every DMA since the guest
expects it has to flush the icache manually in that case.

This fixes random reboot issues on e5500 (booke ppc) for me.

spapr-nvram's drive property is currently connected to a non-existent
"-machine nvram=<drivename>" option.  Instead, tie it to -pflash like
other non-volatile RAM devices.  This provides the following possibilities
for adding a backend for the sPAPR non-volatile RAM:

* -pflash filename

* -drive if=pflash,file=filename,format=raw,...

* -drive if=none,file=filename,format=raw,id=foo,... -global spapr-nvram.drive=foo

There's no good reason to call our bus "pci" rather than let the default
bus name take over ("pci.0").

The big downside to calling it different from anyone else is that tools
that pass -device get confused. They are looking for a bus "pci.0" rather
than "pci".

To make life easier for everyone, let's just drop the name override.

This adds very basic handlers for ibm,get-system-parameter and
ibm,set-system-parameter RTAS calls.

The only parameter handled at the moment is
"platform-processor-diagnostics-run-mode" which is always disabled and
does not support changing. This is expected to make
"ppc64_cpu --run-mode=1" happy.

So far POWER7+ was a part of POWER7 family. However it has a different
PVR base value so in order to support PVR masks, it needs a separate
family class.

This adds a new family class, PVR base and mask values and moves
Power7+ v2.1 CPU to a new family. The class init function is copied
from the POWER7 family.

This defines a firmware name for the new family as "PowerPC,POWER7+"
instead of previously used "PowerPC,POWER7" from the POWER7 family.
The reason for that is that the Sapphire firmware (a h0st firmware)
uses "PowerPC,POWER7+" already and since no specification defines
exactly the CPU nodes naming in the device tree, we better stay
in sync with the host firmware.

IBM POWERPC processors encode PVR as a CPU family in higher 16 bits and
a CPU version in lower 16 bits. Since there is no significant change
in behavior between versions, there is no point to add every single CPU
version in QEMU's CPU list. Also, new CPU versions of already supported
CPU won't break the existing code.

This adds PVR value/mask support for KVM, i.e. for -cpu host option.

As CPU family class name for POWER7 is "POWER7-family", there is no need
to touch aliases.
