Power8E and Power8NVL variants are not of much use in QEMU now, and not
being maintained either.
Power8NVL CPU doesn't boot since skiboot v7.0, or following skiboot commit
to be exact:
commit c5424f683ee3 ("Remove support for POWER8 DD1")
Deprecate the 8E and 8NVL variants.

We deprecated the command line option -old-param for the 10.0
release, which allows us to drop it in 10.2. This option was used to
boot Arm targets with a very old boot protocol using the
'param_struct' ABI. We only ever needed this on a handful of board
types which have all now been removed from QEMU.

Some distros prefer to avoid vendored crate sources, and instead use
local sources from e.g. ``/usr/share/cargo/registry``. Add a
script, inspired by the Mesa spec file(*), that automatically
performs this task. The script is meant to be invoked after unpacking
the QEMU tarball.
(*) This is the hack that Mesa uses:
export MESON_PACKAGE_CACHE_DIR="%{cargo_registry}/"
%define inst_crate_nameversion() %(basename %{cargo_registry}/%{1}-*)
%define rewrite_wrap_file() sed -e "/source.*/d" -e "s/%{1}-.*/%{inst_crate_nameversion %{1}}/" -i subprojects/%{1}.wrap
%rewrite_wrap_file proc-macro2

We don't have any automatic regression tests for these machines and
when asking the usual suspects on the mailing list we came to the
conclusion that nobody tests these machines manually, too, so it seems
like this is currently just completely unused code. Mark them as depre-
cated to see whether anybody still speaks up during the deprecation
period, otherwise we can likely remove these two machines in a couple
of releases.

Both machines were added with little-endian in mind only (the
"endianness" CPU property was hard-wired to "true", see commits
133d23b3ad and a88bbb006a), so the variants that showed up
on the big endian target likely never worked. We deprecated these
non-working machine variants two releases ago, and so far nobody
complained, so it should be fine now to disable them. Hard-wire
the machines to little endian now.

For change, pause, resume, complete, dismiss and finalize actions
corresponding job- and block-job commands are almost equal. The
difference is in find_block_job_locked() vs find_job_locked()
functions. What's different?
1. find_block_job_locked() checks whether the found job is a block-job.
This is OK when moving to more generic API, no needs to document this
change.
2. find_block_job_locked() reports DeviceNotActive on failure, when
find_job_locked() reports GenericError. So, let's document this
difference in deprecated.txt. Still, for dismiss and finalize errors
are not documented at all, so be silent in deprecated.txt as well.

Commit 5b4beba124 ("RISC-V Spike Machines") added the Spike machine and
made it default for qemu-system-riscv32/64. It was the first RISC-V
machine added in QEMU so setting it as default was sensible.
Today we have 7 riscv64 and 6 riscv32 machines and having 'spike' as
default machine is not intuitive. For example, [1] is a bug that was
opened with the 'virt' board in mind, but given that the user didn't
pass a '-machine' option, the user was using 'spike' without knowing.
Being explicit in the command line is desirable when we have a handful
of boards available, so deprecate the default machine setting from
RISC-V.

has been withdrawn from the Linux kernel (i.e. there also won't be

The '-old-param' command line option is specific to Arm targets; it
is very briefly documented as "old param mode". What this option
actually does is change the behaviour when directly booting a guest
kernel, so that command line arguments are passed to the kernel using
the extremely old "param_struct" ABI, rather than the newer ATAGS or
even newer DTB mechanisms.
This support was added back in 2007 to support an old vendor kernel
on the akita/terrier board types:
https://mail.gnu.org/archive/html/qemu-devel/2007-07/msg00344.html
Even then, it was an out-of-date mechanism from the kernel's
point of view -- the kernel has had a comment since 2001 marking
it as deprecated. As of mid-2024, the kernel only retained
param_struct support for the RiscPC and Footbridge platforms:
https://lore.kernel.org/linux-arm-kernel/2831c5a6-cfbf-4fe0-b51c-0396e5b0aeb7@app.fastmail.com/
None of the board types QEMU supports need param_struct support;
mark this option as deprecated.

The pxa2xx CPUs are now only useful with user-mode emulation, because
we dropped all the machine types that used them in 9.2. (Technically
you could alse use "-cpu pxa270" with a board model like versatilepb
which doesn't sanity-check the CPU type, but that has never been a
supported config.)
To use them (or iwMMXt emulation) with QEMU user-mode you would need
to explicitly select them with the -cpu option or the QEMU_CPU
environment variable. A google search finds no examples of anybody
doing this in the last decade; I don't believe the GCC folks are
using QEMU to test their iwMMXt codegen either. In fact, GCC is in
the process of dropping support for iwMMXT entirely.
The iwMMXt emulation is thousands of lines of code in QEMU, and
is now the only bit of Arm insn decode which doesn't use decodetree.
We have no way to test or validate changes to it. This code is
just dead weight that is almost certainly not being used by anybody.
Mark it as deprecated.
