13f934e79f docs: Add license note to the HTML page footer
The standard Sphinx/RTD HTML page footer gives a copyright line
(based on the 'copyright' variable set in conf.py) and a line "Built
with Sphinx using a theme provided by Read the Docs" (which can be
disabled via the html_show_sphinx variable, but we leave it enabled).
As a free software project, we'd like to also mention the license
QEMU and its manual are released under.

Add a template footer.html which defines the 'extrafooter' block that
the RtD theme provides for this purpose.  The new line of text will
go below the existing copyright and sphinx-acknowledgement lines.
(Unfortunately the RTD footer template does not permit putting it
after the copyright but before the sphinx-acknowledgement.)

We use the templating functionality to make the new text also be a
hyperlink to the about/license.html page of the manual.

Unlike rst files, HTML template files are not reported to our depfile
plugin, so we maintain a manual list in meson.build.  New template
files should be rare, so not being able to auto-generate the
dependency info is not too awkward.

we are able to install a package. Different guest configs are tested:
standard, passthrough an strict=0. This is tested with both fedora 31 and
33. The former uses a 5.3 kernel without range invalidation whereas the
latter uses a 5.8 kernel that features range invalidation.

9516034d05 Some qemu updates for IPMI and I2C
Move some ADC file to where they belong and move some sensors to a
 sensor directory, since with new BMCs coming in lots of different
 sensors should be coming in.  Keep from cluttering things up.
 
 Add support for I2C PMBus devices.
 
 Replace the confusing and error-prone i2c_send_recv and i2c_transfer with
 specific send and receive functions.  Several errors have already been
 made with these, avoid any new errors.
 
 Fix the watchdog_expired field in the IPMI watchdog, it's not a bool,
 it's a u8.  After a vmstate transfer, the new value could be wrong.

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

21bde1ecb6 spapr: Fix implementation of Open Firmware client interface
This addresses the comments from v22.

The functional changes are (the VOF ones need retesting with Pegasos2):

(VOF) setprop will start failing if the machine class callback
did not handle it;
(VOF) unit addresses are lowered in path_offset();
(SPAPR) /chosen/bootargs is initialized from kernel_cmdline if
the client did not change it.

fc8c745d50 spapr: Implement Open Firmware client interface
The PAPR platform describes an OS environment that's presented by
a combination of a hypervisor and firmware. The features it specifies
require collaboration between the firmware and the hypervisor.

Since the beginning, the runtime component of the firmware (RTAS) has
been implemented as a 20 byte shim which simply forwards it to
a hypercall implemented in qemu. The boot time firmware component is
SLOF - but a build that's specific to qemu, and has always needed to be
updated in sync with it. Even though we've managed to limit the amount
of runtime communication we need between qemu and SLOF, there's some,
and it has become increasingly awkward to handle as we've implemented
new features.

This implements a boot time OF client interface (CI) which is
enabled by a new "x-vof" pseries machine option (stands for "Virtual Open
Firmware). When enabled, QEMU implements the custom H_OF_CLIENT hcall
which implements Open Firmware Client Interface (OF CI). This allows
using a smaller stateless firmware which does not have to manage
the device tree.

The new "vof.bin" firmware image is included with source code under
pc-bios/. It also includes RTAS blob.

This implements a handful of CI methods just to get -kernel/-initrd
working. In particular, this implements the device tree fetching and
simple memory allocator - "claim" (an OF CI memory allocator) and updates
"/memory@0/available" to report the client about available memory.

This implements changing some device tree properties which we know how
to deal with, the rest is ignored. To allow changes, this skips
fdt_pack() when x-vof=on as not packing the blob leaves some room for
appending.

In absence of SLOF, this assigns phandles to device tree nodes to make
device tree traversing work.

When x-vof=on, this adds "/chosen" every time QEMU (re)builds a tree.

This adds basic instances support which are managed by a hash map
ihandle -> [phandle].

Before the guest started, the used memory is:
0..e60 - the initial firmware
8000..10000 - stack
400000.. - kernel
3ea0000.. - initramdisk

This OF CI does not implement "interpret".

Unlike SLOF, this does not format uninitialized nvram. Instead, this
includes a disk image with pre-formatted nvram.

With this basic support, this can only boot into kernel directly.
However this is just enough for the petitboot kernel and initradmdisk to
boot from any possible source. Note this requires reasonably recent guest
kernel with:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=df5be5be8735

The immediate benefit is much faster booting time which especially
crucial with fully emulated early CPU bring up environments. Also this
may come handy when/if GRUB-in-the-userspace sees light of the day.

This separates VOF and sPAPR in a hope that VOF bits may be reused by
other POWERPC boards which do not support pSeries.

This assumes potential support for booting from QEMU backends
such as blockdev or netdev without devices/drivers used.
