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.

QEMU emulates a *lot* of PowerPC-based machines - having a CPU
that is named "default" and cannot be used with most of those
machines sounds just wrong. Thus let's remove this old and confusing
alias now.

All ppc CPUs represent hardware that exists in the real world, i.e.: we
do not have a "max" CPU with all possible emulated features enabled.
Return the default CPU type for the machine because that has greater
chance of being useful as the "max" CPU.

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.

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.

The addition of the POWER9 CPUs divided the entries for the 970 CPUs,
which is a little bit confusing when you look at the code. So let's
re-group the 970 CPUs together again, and since these chips have been
based on the POWER4 processor, move them also in front of the POWER5
chips now.

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.

compiled/tested since they are under TODO ifdef
which isn't defined in sources.

as regular one with corresponding implementation.

alias pointing to another alias forces lookup code to
do recurrsive translation till real cpu model is reached.
Drop this nonsence and make each alias point to cpu model
that has corresponding CPU type. It will allow to drop
recurrsion in cpu model translation code and actually
make ppc_cpu_aliases[] content use PowerPCCPUAlias
fields properly
(i.e. alias goes into .alias and model goes into .model)
While at it add TODO defines around aliases that point to
cpu models excluded by the same TODO defines.

PPC handles -cpu FOO rather incosistently,
i.e. it does case-insensitive matching of FOO to
a CPU type (see: ppc_cpu_compare_class_name) but
handles alias names as case-sensitive, as result:
# qemu-system-ppc64 -M mac99 -cpu g3
qemu-system-ppc64: unable to find CPU model ' kN�U'
# qemu-system-ppc64 -cpu 970MP_V1.1
qemu-system-ppc64: Unable to find sPAPR CPU Core definition
while
# qemu-system-ppc64 -M mac99 -cpu G3
# qemu-system-ppc64 -cpu 970MP_v1.1
start up just fine.
Considering we can't take case-insensitive matching away,
make it case-insensitive for all alias/type/core_type
lookups.
As side effect it allows to remove duplicate core types
which are the same except of using different cased letters in name.

Replace
"-" TYPE_POWERPC_CPU
when composing cpu type name from cpu model string literal
and the same pattern in format strings with
POWERPC_CPU_TYPE_SUFFIX and POWERPC_CPU_TYPE_NAME(model)
macroses like we do in x86.
Later POWERPC_CPU_TYPE_NAME() will be used to define default
cpu type per machine type and as bonus it will be consistent
and easy grep-able pattern across all other targets that I'm
plannig to treat the same way.

There is no CPU model called "7447_v1.2" in our list, so the

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.
