ppc patch queue 2017-02-02

This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.

This is a long overdue ppc pull request for qemu-2.9. It's been a
long time coming due to some holidays and inconveniently timed
problems with testing. So, there's a lot in here:

* More POWER9 instruction implementations for TCG
* The simpler parts of my CPU compatibility mode cleanup
* This changes behaviour to prefer compatibility modes over
"raW" mode for new machine type versions
* New "40p" machine type which is essentially a modernized and
cleaned up "prep". The intention is that it will replace "prep"
once it has some more testing and polish.
* Add pseries-2.9 machine type
* Implement H_SIGNAL_SYS_RESET hypercall
* Consolidate the two alternate CPU init paths in pseries by
making it always go through CPU core objects to initialize CPU
* A number of bugfixes and cleanups
* Stop the guest timebase when the guest is stopped under KVM.
This makes the guest system clock also stop when paused, which
matches the x86 behaviour.
* Some preliminary cleanups leading towards implementation of the
POWER9 MMU.

There are also some changes not strictly related to ppc code, but for
its benefit:

* Limit the pxi-expander-bridge (PXB) device to x86 guests only
(it's essentially a hack to work around historical x86
limitations)
* Some additions to the 128-bit math in host_utils, necessary for
some of the new instructions.
* Revise a number of qtests and enable them for ppc

Move target-* CPU file into a target/ folder

We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.

powernv: CPU compatibility modes don't make sense for powernv

powernv has some code (derived from the spapr equivalent) used in device
tree generation which depends on the CPU's compatibility mode / logical
PVR. However, compatibility modes don't make sense on powernv - at least
not as a property controlled by the host - because the guest in powernv
has full hypervisor level access to the virtual system, and so owns the
PCR (Processor Compatibility Register) which implements compatiblity modes.

Note: the new logic doesn't take into account kvmppc_smt_threads() like the
old version did. However, if core->nr_threads exceeds kvmppc_smt_threads()
then things will already be broken and clamping the value in the device
tree isn't going to save us.

ppc patch queue 2016-10-28

This pull request supersedes and extends the one from 2016-10-26
(which had a build bug).

Highlights:
* SLOF (pseries guest firmware) update
* Enable a number of extra testcases on ppc / pseries
* Added the 'powernv' machine type
- Almost enough to be minimally usable
- But still missing necessary interrupt controller updates
* Cleanup and consolidation of NVRAM handling on several platforms
with related firmware
* Substantial cleanup to device tree construction
* Some more POWER9 instruction emulation
* Cleanup to handling of pseries option vectors and CAS reboot
handling (host/guest feature negotiation mechanism)
* Significant cleanups to handling of PCI devices in test cases
* New hotplug event infrastructure
* Memory hot unplug support for pseries
* Several bug fixes

The NVRAM cleanup affects some Sun sparc platforms as well as ppc
ones, but have been tested by the sparc maintainer (Mark Cave-Ayland).

The test additions also include substantial general changes to the
test framework that aren't strictly ppc related. They don't seem to
break tests on other platforms, they're for the benefit of enabling
tests on ppc and there isn't a specific maintainer for them, so
they're included in this tree.

As Qemu only supports a single instance of the ISA bus, we use the LPC

That is for later.

The PowerNV machine now has a console. Skiboot should load a kernel
and jump into it but execution will stop quite early because we lack a

ppc/pnv: add a LPC controller

The LPC (Low Pin Count) interface on a POWER8 is made accessible to
the system through the ADU (XSCOM interface). This interface is part
of set of units connected together via a local OPB (On-Chip Peripheral
Bus) which act as a bridge between the ADU and the off chip LPC
endpoints, like external flash modules.

The most important units of this OPB are :
- OPB Master: contains the ADU slave logic, a set of internal
registers and the logic to control the OPB.
- LPCHC (LPC HOST Controller): which implements a OPB Slave, a set of
internal registers and the LPC HOST Controller to control the LPC
interface.

Four address spaces are provided to the ADU :
- LPC Bus Firmware Memory
- LPC Bus Memory
- LPC Bus I/O (ISA bus)
- and the registers for the OPB Master and the LPC Host Controller

On POWER8, an intermediate hop is necessary to reach the OPB, through
a unit called the ECCB. OPB commands are simply mangled in ECCB write
commands.

On POWER9, the OPB master address space can be accessed via MMIO. The
logic is same but the code will be simpler as the XSCOM and ECCB hops
are not necessary anymore.

This version of the LPC controller model doesn't yet implement support
for the SerIRQ deserializer present in the Naples version of the chip
though some preliminary work is there.

ppc/pnv: add XSCOM infrastructure

On a real POWER8 system, the Pervasive Interconnect Bus (PIB) serves
as a backbone to connect different units of the system. The host
firmware connects to the PIB through a bridge unit, the
Alter-Display-Unit (ADU), which gives him access to all the chiplets
on the PCB network (Pervasive Connect Bus), the PIB acting as the root
of this network.

XSCOM (serial communication) is the interface to the sideband bus
provided by the POWER8 pervasive unit to read and write to chiplets
resources. This is needed by the host firmware, OPAL and to a lesser
extent, Linux. This is among others how the PCI Host bridges get
configured at boot or how the LPC bus is accessed.

To represent the ADU of a real system, we introduce a specific
AddressSpace to dispatch XSCOM accesses to the targeted chiplets. The
translation of an XSCOM address into a PCB register address is
slightly different between the P9 and the P8. This is handled before
the dispatch using a 8byte alignment for all.

To customize the device tree, a QOM InterfaceClass, PnvXScomInterface,
is provided with a populate() handler. The chip populates the device
tree by simply looping on its children. Therefore, each model needing
custom nodes should not forget to declare itself as a child at
instantiation time.

This is is an abstraction of a POWER8 chip which is a set of cores
plus other 'units', like the pervasive unit, the interrupt controller,

be seen as a socket. It depends on a cpu model and its characteristics:
max cores and specific inits are defined in a PnvChipClass.

We start with an near empty PnvChip with only a few cpu constants
which we will grow in the subsequent patches with the controllers
required to run the system.

The Chip CFAM (Common FRU Access Module) ID gives the model of the
chip and its version number. It is generally the first thing firmwares
fetch, available at XSCOM PCB address 0xf000f, to start initialization.
