ppc patch queue for 2022-12-21:

This queue contains a MAINTAINERS update, the implementation of the Freescale eSDHC,
the introduction of the DEXCR/HDEXCR instructions and other assorted fixes (most of
them for the e500 board).

ppc patch queue for 2022-10-29:

This queue has the second part of the ppc4xx_sdram cleanups, doorbell
instructions for POWER8, new pflash handling for the e500 machine and a
Radix MMU regression fix.

It also has a lot of performance optimizations in the PowerPC emulation
done by the researchers of the Eldorado institute. Between using gvec
for VMX/VSX instructions, a full rework of the interrupt model and PMU
optimizations, they managed to drastically speed up the emulation of
powernv8/9/10 machines. Here's an example with avocado tests:

- with master:

tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8:
PASS (38.89 s)
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9:
PASS (43.89 s)

- with this queue applied:

tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv8:
PASS (21.23 s)
tests/avocado/boot_linux_console.py:BootLinuxConsole.test_ppc_powernv9:
PASS (22.58 s)

Other ppc machines, like pseries, also had a noticeable performance
boost.

hw/ppc/e500: Implement pflash handling

Allows e500 boards to have their root file system reside on flash using
only builtin devices located in the eLBC memory region.

Note that the flash memory area is only created when a -pflash argument is
given, and that the size is determined by the given file. The idea is to
put users into control.

The documentation suggests that there is a qemu-system-ppc32 binary
while the 32 bit version is actually just named qemu-system-ppc. Settle
on qemu-system-ppc64 which also works for 32 bit machines and causes
less clutter in the documentation.

in the maintainership of the project, a new QMP/HMP command and bug
fixes:

- Cedric is stepping back from qemu-ppc maintainership;
- ppc4xx_sdram: QOMification and clean ups;
- e500: add new types of flash and clean ups;
- QMP/HMP: introduce dumpdtb command;
- spapr_pci, booke doorbell interrupt and xvcmp* bit fixes;

The 'dumpdtb' implementation is also making changes to RISC-V files that
were acked by Alistair Francis and are being included in this queue.

ppc patch queue 2021-07-09

Here's a (probably) final pull request before the qemu-6.1 soft
freeze. Includes:
* Implementation of the new H_RPT_INVALIDATE hypercall
* 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.
This will allow more flexible handling of possible future CPU
Spectre-like flaws
* Correctly treat mtmsrd as an illegal instruction on BookE cpus
* Firmware update for the ppce500 machine type
