These days the Arm architecture has a wide range of fine-grained
optional extra architectural features. We implement quite a lot
of these but by no means all of them. Document what we do implement,
so that users can find out without having to dig through back-issues
of our Changelog on the wiki.

It is useful to know which CPUs satisfy each x86-64 ABI
compatibility level, when dealing with guest OS that require
something newer than the baseline ABI.
These ABI levels are defined in:

QEMU 5.1 changed the behaviour of the default boot for the RISC-V virt

target-riscv.rst.

At present the Microchip Icicle Kit machine only supports using
'-bios' to load the HSS, and does not support '-kernel' for direct
kernel booting just like other RISC-V machines do. One has to use
U-Boot which is chain-loaded by HSS, to load a kernel for testing.
This is not so convenient.
Adding '-kernel' support together with the existing '-bios', we
follow the following table to select which payload we execute:
-bios | -kernel | payload
------+------------+--------
N | N | HSS
Y | don't care | HSS
N | Y | kernel
This ensures backwards compatibility with how we used to expose
'-bios' to users. When '-kernel' is used for direct boot, '-dtb'
must be present to provide a valid device tree for the board,
as we don't generate device tree.
When direct kernel boot is used, the OpenSBI fw_dynamic BIOS image
is used to boot a payload like U-Boot or OS kernel directly.
Documentation is updated to describe the direct kernel boot. Note
as of today there is still no PolarFire SoC support in the upstream
Linux kernel hence the document does not include instructions for
that. It will be updated in the future.

The 4.x branch of Sphinx introduces a breaking change, as generated man
pages are now written to subdirectories corresponding to the manual
section they belong to. This results in `make install` erroring out when
attempting to install the man pages, because they are not where it
expects to find them.
This patch restores the behavior of Sphinx 3.x regarding man pages.

Next batch of ppc target patches. Highlights are:
* A fix for a regression with single-step mode
* Start of moving ppc to use decodetree
* Implementation of some POWER10 64-bit prefixed instructions
* Several cleanups to softmmu code
* Continued progress towards allowing --disable-tcg
* Fix for the POWER PEF implementation
* Fix for LPCR handling of hotplugged CPUs
* Assorted other bugfixes and cleanups
This patchset does contain a couple of changes to code outside my
normal scope of maintainership, related to the removal of cpu_dump and
cpu_statistics hooks. ppc was the last target arch implementing these
at all, and they didn't really do anything there either. The patches

The contents of this patch were initially developed and posted by Han
Han[1], however, it appears the original patch was not applied. Since
then, the relevant documentation has been moved and adapted to a new
format.
I've taken most of the original wording and tweaked it according to
some of the feedback from the original patch submission. I've also
adapted it to restructured text, which is the format the documentation
currently uses.

The default "alabaster" sphinx theme has a couple shortcomings:
- the navbar moves along the page
- the search bar is not always at the same place
- it lacks some contrast and colours
The "rtd" theme from readthedocs.org is a popular third party theme used
notably by the kernel, with a custom style sheet. I like it better,
perhaps others do too. It also simplifies the "Edit on Gitlab" links.
Tweak a bit the custom theme to match qemu.org style, use the
QEMU logo, and favicon etc.

There are no known users of this CPU anymore, and there are no
binaries available online which could be used for regression tests,
so the code has likely completely bit-rotten already. It's been
marked as deprecated since two releases now and nobody spoke up
that there is still a need to keep it, thus let's remove it now.

The AN524 FPGA image supports two memory maps, which differ in where
the QSPI and BRAM are. In the default map, the BRAM is at
0x0000_0000, and the QSPI at 0x2800_0000. In the second map, they
are the other way around.
In hardware, the initial mapping can be selected by the user by
writing either "REMAP: BRAM" (the default) or "REMAP: QSPI" in the
board configuration file. The board config file is acted on by the
"Motherboard Configuration Controller", which is an entirely separate
microcontroller on the dev board but outside the FPGA.
The guest can also dynamically change the mapping via the SCC
CFG_REG0 register.
Implement this functionality for QEMU, using a machine property
"remap" with valid values "BRAM" and "QSPI" to allow the user to set
the initial mapping, in the same way they can on the FPGA, and
wiring up the bit from the SCC register to also switch the mapping.
