target/ppc: Add POWER9 DD2.2 model

POWER9 DD2.1 and earlier had significant limitations when running KVM,
including lack of "mixed mode" MMU support (ability to run HPT and RPT
mode on threads of the same core), and a translation prefetch issue
which is worked around by disabling "AIL" mode for the guest.

These processors are not widely available, and it's difficult to deal
with all these quirks in qemu +/- KVM, so create a POWER9 DD2.2 CPU
and make it the default POWER9 CPU.

target/ppc: Use SMT4 small core chip type in POWER9/10 PVRs

QEMU's PVR value for POWER9 DD2.0 has chip type 1, which is the SMT4
"small core" type that OpenPOWER processors use. QEMU's PVR for all
other POWER9/10 have chip type 0, which "enterprise" systems use.

The difference does not really matter to QEMU (because it does not care
about SMT mode in the target), but for consistency all PVRs should use
the same chip type. We'll go with the SMT4 OpenPOWER type.

target/ppc: Fix MPC8555 and MPC8560 core type to e500v1

Commit 80d11f4467c4 ("Add definitions for Freescale PowerPC implementations")
changed core type of MPC8555 and MPC8560 from e500v1 to e500v2.

target/ppc: Fix MPC8555 and MPC8560 core type to e500v1

Commit 80d11f4467c4 ("Add definitions for Freescale PowerPC implementations")
changed core type of MPC8555 and MPC8560 from e500v1 to e500v2.

But both MPC8555 and MPC8560 have just e500v1 cores, there are no features
of e500v2 cores. It can be verified by reading NXP documentations:
https://www.nxp.com/docs/en/data-sheet/MPC8555EEC.pdf
https://www.nxp.com/docs/en/data-sheet/MPC8560EC.pdf
https://www.nxp.com/docs/en/reference-manual/MPC8555ERM.pdf
https://www.nxp.com/docs/en/reference-manual/MPC8560RM.pdf

Therefore fix core type of MPC8555 and MPC8560 back to e500v1.

Just for completeness, here is list of all Motorola/Freescale/NXP
processors which were released and have e500v1 or e500v2 cores:

e500v1: MPC8540 MPC8541 MPC8555 MPC8560

e500v2: BSC9131 BSC9132
C291 C292 C293
MPC8533 MPC8535 MPC8536 MPC8543 MPC8544 MPC8545 MPC8547
MPC8548 MPC8567 MPC8568 MPC8569 MPC8572
P1010 P1011 P1012 P1013 P1014 P1015 P1016 P1020 P1021
P1022 P1024 P1025 P2010 P2020

Sorted alphabetically; not by release date / generation / feature set.
All this is from public information available on NXP website.

Seems that qemu has support only for some subset of MPC85xx processors.
Historically processors with e500 cores have mpc85xx family codename and
lot of software have them in mpc85xx architecture subdirectory.

Note that GCC uses -mcpu=8540 option for specifying e500v1 core and
-mcpu=8548 option for specifying e500v2 core.

So sometimes (mpc)8540 is alias for e500v1 and (mpc)8548 is alias for
e500v2.

target/ppc: Remove PowerPC 601 CPUs

The PowerPC 601 processor is the first generation of processors to
implement the PowerPC architecture. It was designed as a bridge
processor and also could execute most of the instructions of the
previous POWER architecture. It was found on the first Macs and IBM
RS/6000 workstations.

There is not much interest in keeping the CPU model of this
POWER-PowerPC bridge processor. We have the 603 and 604 CPU models of
the 60x family which implement the complete PowerPC instruction set.

ppc patch queue 2021-08-27

First ppc pull request for qemu-6.2. As usual, there's a fair bit
here, since it's been queued during the 6.1 freeze. Highlights are:

* Some fixes for 128 bit arithmetic and some vector opcodes that use
them
* Significant improvements to the powernv to support POWER10 cpus
(more to come though)
* Several cleanups to the ppc softmmu code
* A few other assorted fixes

ppc: Add a POWER10 DD2 CPU

The POWER10 DD2 CPU adds an extra LPCR[HAIL] bit. DD1 doesn't have
HAIL but since it does not break the modeling and that we don't plan
to support DD1, modify the LPCR mask of all the POWER10 family.

Setting the HAIL bit is a requirement to support the scv instruction
on PowerNV POWER10 platforms since glibc-2.33.

target/ppc: Add POWER9 DD2.0 model information

At the moment the only POWER9 model which is listed in qemu is v1.0 (aka
"DD1"). This is a very early (read, buggy) version which will never be
released to the public - it was included in qemu only for the convenience
of those doing bringup on the early silicon. For bonus points, we actually
had its PVR incorrect in the table (0x004e0000 instead of 0x004e0100). We
also never actually implemented the differences in behaviour (read, bugs)
that marked DD1 in qemu.

Now that we know the PVR for the substantially better v2.0 (DD2) chip,
include it and make it the default POWER9 in qemu. For the time being we
leave the DD1 definition in place for the poor souls (read, me) who still
need to work with DD1 hardware.
