8700ee15de hw/cxl: Standardize all references on CXL r3.1 and minor updates
Previously not all references mentioned any spec version at all.
Given r3.1 is the current specification available for evaluation at
www.computeexpresslink.org update references to refer to that.
Hopefully this won't become a never ending job.

A few structure definitions have been updated to add new fields.
Defaults of 0 and read only are valid choices for these new DVSEC
registers so go with that for now.

There are additional error codes and some of the 'questions' in
the comments are resolved now.

Update documentation reference to point to the CXL r3.1 specification
with naming closer to what is on the cover.

For cases where there are structure version numbers, add defines
so they can be found next to the register definitions.

1eeb432a95 doc/sphinx/hxtool.py: add optional label argument to SRST directive
We can't just embed labels directly into files like qemu-options.hx which
are included from multiple top-level rST files, because Sphinx sees the
labels as duplicate: https://github.com/sphinx-doc/sphinx/issues/9707

So add an optional argument to the SRST directive which causes a label
of the form '.. _DOCNAME-HXFILE-LABEL:' to be emitted, where 'DOCNAME'
is the name of the top level rST file, 'HXFILE' is the filename of the
.hx file, and 'LABEL' is the text provided within the 'SRST()' directive.
Using the DOCNAME of the top-level rST document means that it is unique
even when the .hx file is included from two different documents, as is
the case for qemu-options.hx

Now where the Xen PV documentation refers to the documentation for the
-initrd command line option, it can emit a link directly to it as
'<system/invocation-qemu-options-initrd>'.

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.

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.

41581f1361 hw/arm: Add minimal support for the B-L475E-IOT01A board
This commit adds a new B-L475E-IOT01A board using the STM32L475VG SoC
as well as a dedicated documentation file.
The implementation is derived from the Netduino Plus 2 machine.
There are no peripherals implemented yet, only memory regions.

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.

  - Use better title for the machine type
  - Explain why Xen is a little different
  - Add a proper anchor to the tpm-device link

13edcf591e hw/arm/vexpress-a9: Remove useless mapping of RAM at address 0
On the vexpress-a9 board we try to map both RAM and flash to address 0,
as seen in "info mtree":

address-space: memory
  0000000000000000-ffffffffffffffff (prio 0, i/o): system
    0000000000000000-0000000003ffffff (prio 0, romd): alias vexpress.flashalias @vexpress.flash0 0000000000000000-0000000003ffffff
    0000000000000000-0000000003ffffff (prio 0, ram): alias vexpress.lowmem @vexpress.highmem 0000000000000000-0000000003ffffff
    0000000010000000-0000000010000fff (prio 0, i/o): arm-sysctl
    0000000010004000-0000000010004fff (prio 0, i/o): pl041
(etc)

The flash "wins" and the RAM mapping is useless (but also harmless).

This happened as a result of commit 6ec1588e in 2014, which changed
"we always map the RAM to the low addresses for vexpress-a9" to "we
always map flash in the low addresses", but forgot to stop mapping
the RAM.

In real hardware, this low part of memory is remappable, both at
runtime by the guest writing to a control register, and configurably
as to what you get out of reset -- you can have the first flash
device, or the second, or the DDR2 RAM, or the external AXI bus
(which for QEMU means "nothing there").  In an ideal world we would
support that remapping both at runtime and via a machine property to
select the out-of-reset behaviour.

Pending anybody caring enough to implement the full remapping
behaviour:
 * remove the useless mapped-but-inaccessible lowram MR

bb1cff6ee0 docs/specs/ivshmem-spec: Convert to rST
Convert docs/specs/ivshmem-spec.txt to rST format.

In converting, I have dropped the sections on the device's command
line interface and usage, as they are already covered by the
user-facing docs in system/devices/ivshmem.rst.

I have also removed the reference to Memnic, because the URL is dead
and a web search suggests that whatever this was it's pretty much
sunk without trace.

dfff1000fe target/arm: Implement Neoverse N2 CPU model
Implement a model of the Neoverse N2 CPU. This is an Armv9.0-A
processor very similar to the Cortex-A710. The differences are:
 * no FEAT_EVT
 * FEAT_DGH (data gathering hint)
 * FEAT_NV (not yet implemented in QEMU)
 * Statistical Profiling Extension (not implemented in QEMU)
 * 48 bit physical address range, not 40
 * CTR_EL0.DIC = 1 (no explicit icache cleaning needed)
 * PMCR_EL0.N = 6 (always 6 PMU counters, not 20)

Because it has 48-bit physical address support, we can use
this CPU in the sbsa-ref board as well as the virt board.

aa0c9aec57 hw/i386/pc_piix: Make PIIX4 south bridge usable in PC machine
QEMU's PIIX3 implementation actually models the real PIIX4, but with different
PCI IDs. Usually, guests deal just fine with it. Still, in order to provide a
more consistent illusion to guests, allow QEMU's PIIX4 implementation to be used
in the PC machine.

3d80bbf1f6 target/arm: Implement FEAT_HPMN0
FEAT_HPMN0 is a small feature which defines that it is valid for
MDCR_EL2.HPMN to be set to 0, meaning "no PMU event counters provided
to an EL1 guest" (previously this setting was reserved). QEMU's
implementation almost gets HPMN == 0 right, but we need to fix
one check in pmevcntr_is_64_bit(). That is enough for us to
advertise the feature in the 'max' CPU.

(We don't need to make the behaviour conditional on feature
presence, because the FEAT_HPMN0 behaviour is within the range
of permitted UNPREDICTABLE behaviour for a non-FEAT_HPMN0
implementation.)

3039b090f2 target/arm: Implement FEAT_HBC
FEAT_HBC (Hinted conditional branches) provides a new instruction
BC.cond, which behaves exactly like the existing B.cond except
that it provides a hint to the branch predictor about the
likely behaviour of the branch.

Since QEMU does not implement branch prediction, we can treat
this identically to B.cond.
