target/ppc: Introduce a vhyp framework for nested HV support

Introduce virtual hypervisor methods that can support a "Nested KVM HV"
implementation using the bare metal 2-level radix MMU, and using HV
exceptions to return from H_ENTER_NESTED (rather than cause interrupts).

HV exceptions can now be raised in the TCG spapr machine when running a
nested KVM HV guest. The main ones are the lev==1 syscall, the hdecr,
hdsi and hisi, hv fu, and hv emu, and h_virt external interrupts.

HV exceptions are intercepted in the exception handler code and instead
of causing interrupts in the guest and switching the machine to HV mode,
they go to the vhyp where it may exit the H_ENTER_NESTED hcall with the
interrupt vector numer as return value as required by the hcall API.

Address translation is provided by the 2-level page table walker that is
implemented for the bare metal radix MMU. The partition scope page table
is pointed to the L1's partition scope by the get_pate vhc method.

ppc patch queue for 2021-11-09

Here's the latest set of ppc related patches for qemu-6.2, which I
hope will squeeze in just barely before the hard freeze.

This set includes a change to MAINTAINERS moving maintainership of ppc
from myself and Greg Kurz to Cédric le Goater and Daniel Henrique
Barboza. So, I expect this to be my last pull request as ppc
maintainer. It's been great, but it's time I moved onto other things.

Apart from that, this patchset is mostly a lot of updates to TCG
implementations of ISA 3.1 (POWER10) instructions from the El Dorado
team. There are also a handful of other fixes.

Instead of relying on the mapped address of the MV64361 registers
access them via their memory region. This is not a problem at reset
time when these registers are mapped at the default address but the
guest could change this later and then the RTAS calls accessing PCI
config registers could fail. None of the guests actually do this so
this only avoids a theoretical problem not seen in practice.

* Virtual Open Firmware for pSeries and pegasos2 machine types.
This is an experimental minimal Open Firmware implementation which
works by delegating nearly everything to qemu itself via a special
hypercall.
* A number of cleanups to the ppc soft MMU code
* Fix to handling of two-level radix mode translations for the
powernv machine type
* Update the H_GET_CPU_CHARACTERISTICS call with newly defined bits.

ppc/pegasos2: Implement some RTAS functions with VOF

Linux uses RTAS functions to access PCI devices so we need to provide
these with VOF. Implement some of the most important functions to
allow booting Linux with VOF. With this the board is now usable
without a binary ROM image and we can enable it by default as other
boards.

ppc/pegasos2: Use Virtual Open Firmware as firmware replacement

The pegasos2 board comes with an Open Firmware compliant ROM based on
SmartFirmware but it has some changes that are not open source
therefore the ROM binary cannot be included in QEMU. Guests running on
the board however depend on services provided by the firmware. The
Virtual Open Firmware recently added to QEMU implements a minimal set
of these services to allow some guests to boot without the original
firmware. This patch adds VOF as the default firmware for pegasos2
which allows booting Linux and MorphOS via -kernel option while a ROM
image can still be used with -bios for guests that don't run with VOF.

ppc patch queue 2021-05-04

Here's the first ppc pull request for qemu-6.1. It has a wide variety
of stuff accumulated during the 6.0 freeze. Highlights are:

* Multi-phase reset cleanups for PAPR
* Preliminary cleanups towards allowing !CONFIG_TCG for the ppc target
* Cleanup of AIL logic and extension to POWER10
* Further improvements to handling of hot unplug failures on PAPR
* Allow much larger numbers of CPU on pseries
* Support for the H_SCM_HEALTH hypercall
* Add support for the Pegasos II board
* Substantial cleanup to hflag handling
* Assorted minor fixes and cleanups

hw/ppc: Add emulation of Genesi/bPlan Pegasos II

Add new machine called pegasos2 emulating the Genesi/bPlan Pegasos II,
a PowerPC board based on the Marvell MV64361 system controller and the
VIA VT8231 integrated south bridge/superio chips. It can run Linux,
AmigaOS and a wide range of MorphOS versions. Currently a firmware ROM
image is needed to boot and only MorphOS has a video driver to produce
graphics output. Linux could work too but distros that supported this
machine don't include usual video drivers so those only run with
serial console for now.
