1acf215998 docs/system/arm/virt.rst: Add note on CPU features off by default
Add a note on CPU features that are off by default in `virt` machines.
Some CPU features will remain off even if a CPU-capable CPU (e.g.,
`-cpu max`) is selected because they require support in both the CPU
itself and in the wider system. Therefore, the user, besides selecting a
CPU that supports such features, must also turn on the feature using a
machine option.

43eef24f52 hw/arm: Add EHCI/OHCI controllers to Allwinner R40 and Bananapi board
Allwinner R40 supports two USB host ports shared between a USB 2.0 EHCI
host controller and a USB 1.1 OHCI host controller. Add support for both
of them.

If machine USB support is not enabled, create unimplemented devices
for the USB memory ranges to avoid crashes when booting Linux.

c8cdec74e6 hw/block: Deprecate the TC58128 block device
The 16MiB flash device is only used by the deprecated shix machine.
Its code it old and unmaintained, and has never been adapted to the
QOM architecture. It still contains debug statements and uses global
variables. It is time to deprecate it.

322b038c94 target/sh4: Deprecate the shix machine
The shix machine has been designed and used at Télécom Paris from 2003
to 2010. It had been added to QEMU in 2005 and has not been maintained
since. Since nobody is using the physical board anymore nor interested
in maintaining the QEMU port, it is time to deprecate it.

f6bbac985e docs/migration: Create index page
Create an index page for migration module.  Move VFIO migration there too.
A trivial touch-up on the title to use lower case there.

Since then we'll have "migration" as the top title, make the main doc file
renamed to "migration framework".

8cb2f8b172 docs/migration: Create migration/ directory
Migration documentation is growing into a single file too large.  Create a
sub-directory for it for a split.

We also already have separate vfio/virtio documentations, move it all over
into the directory.

Note that the virtio one is still not yet converted to rST.  That is a job
for later.

Although very similar to the STM32F4xx EXTI, STM32L4x5 EXTI generates
more than 32 event/interrupt requests and thus uses more registers
than STM32F4xx EXTI which generates 23 event/interrupt requests.

d95f260aee docs/devel/docs: Document .hx file syntax
We don't currently document the syntax of .hx files anywhere
except in a few comments at the top of individual .hx files.
We don't even have somewhere in the developer docs where we
could do this.

Add a new files docs/devel/docs.rst which can be a place to
document how our docs build process works. For the moment,
put in only a brief introductory paragraph and the documentation
of the .hx files. We could later add to this file by for
example describing how the QAPI-schema-to-docs process works,
or anything else that developers might need to know about
how to add documentation.

Make the .hx files refer to this doc file, and clean
up their header comments to be more accurate for the
usage in each file and less cut-n-pasted.

e0299f71b3 docs/system/riscv: sifive_u: Update S-mode U-Boot image build instructions
Currently, the documentation outlines the process for building the
S-mode U-Boot image using `make menuconfig` and manual actions within
the menuconfig UI. However, this approach is fragile due to Kconfig
options potentially changing across different releases. For example,
CONFIG_OF_PRIOR_STAGE has been replaced by CONFIG_BOARD since v2022.01
release, and CONFIG_TEXT_BASE has been moved to the 'General setup'
menu from the 'Boot options' menu in v2024.01 release.

This update aims to make the S-mode U-Boot image build instructions
future-proof. It leverages the 'config' script provided in the U-Boot
source tree to edit the .config file, followed by a `make olddefconfig`.

Validated with U-Boot v2024.01 release.

fd49b2153e qemu-options: Clarify handling of commas in options parameters
Provide explicit guidance on dealing with option parameters as arbitrary
strings containing commas, such as in "file=my,file" and "string=a,b". The
updated documentation emphasizes the need to double commas when they
appear within such parameters.

c455e011c6 hw: Replace anti-social QOM type names (again)
QOM type names containing ',' result in awful UI.  We got rid of them
in v6.0.0 (commit e178113ff6 hw: Replace anti-social QOM type names).
A few have crept back since:

    xlnx,cframe-reg
    xlnx,efuse
    xlnx,pmc-efuse-cache
    xlnx,versal-cfu-apb
    xlnx,versal-cfu-fdro
    xlnx,versal-cfu-sfr
    xlnx,versal-crl
    xlnx,versal-efuse
    xlnx,zynqmp-efuse

These are all device types.  They can't be plugged with -device /
device_add, except for "xlnx,efuse" (I'm not sure that one is
intentional).

They *can* be used with -device / device_add to request help.
Usability is poor, though: you have to double the comma, like this:

    $ qemu-system-aarch64 -device xlnx,,pmc-efuse-cache,help

They can also be used with -global, where you must *not* double the
comma:

    $ qemu-system-aarch64 -global xlnx,efuse.drive-index=2

Trap for the unwary.

"xlnx,efuse", "xlnx,versal-efuse", "xlnx,pmc-efuse-cache",
"xlnx-zynqmp-efuse" are from v6.2.0, "xlnx,versal-crl" is from v7.1.0,
and the remainder are new.

Rename them all to "xlnx-FOO", like commit e178113ff6 did.
