pseries: FDT NUMA extensions to support multi-node guests

Add NUMA specific properties to guest's device tree to boot a multi-node
guests. This patch adds the following properties:

ibm,associativity
ibm,architecture-vec-5
ibm,associativity-reference-points...

pseries: Add partial support for PCI

This patch adds a PCI bus to the pseries machine. This instantiates
the qemu generic PCI bus code, advertises a PCI host bridge in the
guest's device tree and implements the RTAS methods specified by PAPR
to access PCI config space. It also sets up the memory regions we...

pseries: Refactor spapr irq allocation

Paulo Bonzini changed the original spapr code, which manually assigned irq
numbers for each virtual device, to allocate them automatically from the
device initialization. That allowed spapr virtual devices to be constructed...

pseries: Implement set-time-of-day RTAS function

Currently there is no implementation for set-time-of-day rtas function,
which causes the following warning "setting the clock failed (-1)" on
the guest.

This patch just creates this function, get the timedate diff and store in...

pseries: More complete WIMG validation in H_ENTER code

Currently our implementation of the H_ENTER hypercall, which inserts a
mapping in the hash page table assumes that only ordinary memory is ever
mapped, and only permits mapping attribute bits accordingly (WIMG==0010)....

spapr: proper qdevification

Right now the spapr devices cannot be instantiated with -device,
because the IRQs need to be passed to the spapr_*_create functions.
Do this instead in the bus's init wrapper.

This is particularly important with the conversion from scsi-disk...

Delay creation of pseries device tree until reset

At present, the 'pseries' machine creates a flattened device tree in the
machine->init function to pass to either the guest kernel or to firmware.

However, the machine->init function runs before processing of -device...

Implement hcall based RTAS for pSeries machines

On pSeries machines, operating systems can instantiate "RTAS" (Run-Time
Abstraction Services), a runtime component of the firmware which implements
a number of low-level, infrequently used operations. On logical partitions...

Implement the PAPR (pSeries) virtualized interrupt controller (xics)

PAPR defines an interrupt control architecture which is logically divided
into ICS (Interrupt Control Presentation, each unit is responsible for
presenting interrupts to a particular "interrupt server", i.e. CPU) and...

Start implementing pSeries logical partition machine

This patch adds a "pseries" machine to qemu. This aims to emulate a
logical partition on an IBM pSeries machine, compliant to the
"PowerPC Architecture Platform Requirements" (PAPR) document.

This initial version is quite limited, it implements a basic machine...

Implement the bus structure for PAPR virtual IO

This extends the "pseries" (PAPR) machine to include a virtual IO bus
supporting the PAPR defined hypercall based virtual IO mechanisms.

So far only one VIO device is provided, the vty / vterm, providing
a full console (polled only, for now)....
