The goal is to emulate a PowerNV system at the level of the skiboot
firmware, which loads the OS and provides some runtime services. Power
Systems have a lower firmware (HostBoot) that does low level system
initialization, like DRAM training. This is beyond the scope of what
qemu will address in a PowerNV guest.
No devices yet, not even an interrupt controller. Just to get started,
some RAM to load the skiboot firmware, the kernel and initrd. The
device tree is fully created in the machine reset op.

Currently the "platform-bus" device is included for all softmmu builds.
This bridge is intended for use on any platforms that require dynamic
creation of sysbus devices. However, at present it is used only for the
PPC E500 target, with plans for the ARM "virt" target in the immediate
future.
To avoid a not-very-useful entry appearing in "qemu -device ?" output on
other targets, this patch makes a specific config option for platform-bus
and enables it (for now) only on ppc configurations which include E500
and on ARM (which always includes the "virt" target).

Recent (host) kernels support emulating the PAPR defined "XICS" interrupt
controller system within KVM. This patch allows qemu to initialize and
configure the in-kernel XICS, and keep its state in sync with qemu's XICS
state as necessary.
This should give considerable performance improvements. e.g. on a simple
IPI ping-pong test between hardware threads, using qemu XICS gives us
around 5,000 irqs/second, whereas the in-kernel XICS gives us around
70,000 irqs/s on the same hardware configuration.

pci-hotplug.c and the CONFIG_PCI_HOTPLUG variable which controls its
compilation are misnamed. They're not about PCI hotplug in general, but
rather about the pci_add/pci_del interface which are now deprecated in
favour of the more general device_add/device_del interface. This patch
therefore renames them to pci-hotplug-old.c and CONFIG_PCI_HOTPLUG_OLD.
CONFIG_PCI_HOTPLUG=y was listed twice in {i386,x86_64}-softmmu.make for no
particular reason, so we clean that up too. In addition it was included in
ppc64-softmmu.mak for which the old hotplug interface was never used and is
unsuitable, so we remove that too.
Most of pci-hotplug.c was additionaly protected by #ifdef TARGET_I386. The
small piece which wasn't is only called from the pci_add and pci_del hooks
in hmp-commands.hx, which themselves were protected by #ifdef TARGET_I386.
This patch therefore also removes the #ifdef from pci-hotplug-old.c,
and changes the ifdefs in hmp-commands.hx to use CONFIG_PCI_HOTPLUG_OLD.

Enables support for the in-kernel MPIC that thas been merged into the
KVM next branch. This includes irqfd/KVM_IRQ_LINE support from Alex
Graf (along with some other improvements).
Note from Alex regarding kvm_irqchip_create():
On x86, one would call kvm_irqchip_create() to initialize an
in-kernel interrupt controller. That function then goes ahead and
initializes global capability variables as well as the default irq
routing table.
On ppc, we can't call kvm_irqchip_create() because we can have
different types of interrupt controllers. So we want to do all the
things that function would do for us in the in-kernel device init
handler.

As soon as virtio-pci.c gets compiled and used on S390 the internal qdev magic
gets confused and tries to give us PCI devices instead of S390 virtio devices.
Since we don't have PCI on S390, we can safely not compile virtio-pci at all.
In order to do this I added a new config option "CONFIG_VIRTIO_PCI" that I
enabled for every platform except S390. Thanks to this the change should be a
complete nop for every other platform.
