[PATCH 0/7] docs/system/arm: Provide at least skeleton docs for all boards

[PATCH 0/7] docs/system/arm: Provide at least skeleton docs for all boards

[Peter Maydell]

In target-arm.rst there is an apologetic note:

  Unfortunately many of the Arm boards QEMU supports are currently
  undocumented; you can get a complete list by running
  ``qemu-system-aarch64 --machine help``.

However, the situation isn't actually as bleak as this suggests:
over the years we have generally insisted on documentation for
new machine types and have filled in some of the gaps where
there was no documentation for older machine types. Plus we just
deleted a lot of older undocumented or underdocumented boards.

I did a check of all the board types listed in --help and we
really don't have very many left that weren't listed in the
documentation. This series does some cleanup of existing
docs to ensure that every board covered by a .rst file has
a line in the right place in the list that lists the board
name explicitly. It then adds placeholder docs for the remaining
undocumented boards:
 * nuri, smdkc210 (Exynos4 boards)
 * xlnx-zcu102
 * mcimx6ul-evk
 * mcimx7d-sabre

and removes the apologetic note about the list being incomplete.

The placeholder docs are obviously not very useful, but they
mean we at least have an entry in the list for the board
that gives the manufacturer's name for the board, and we
have a place to put expanded information in future if anybody
wants to write it.

Anybody who has more information on the above boards is of
course welcome to expand on the minimal files here :-)

thanks

[PATCH 2/7] docs/system/arm: Don't use wildcard '*-bmc' in doc titles

[Peter Maydell]

We have two Arm board doc files which both use '*-bmc' in their
documentation title. The result is that when you read the
table of contents in system/target-arm.html you don't know
which boards are covered by which file.

Expand out the board names entirely in the document titles.

[PATCH 3/7] docs/system/arm: Split fby35 out from aspeed.rst

[Peter Maydell]

The fby35 machine is not implemented in hw/arm/aspeed.c,
but its documentation is currently stuck at the end of aspeed.rst,
formatted in a way that it gets its own heading in the top-level
list of boards in target-arm.html.

We don't have any other boards that we document like this; split it
out into its own rst file. This improves consistency with other
board docs and means we can have the entry in the target-arm
list be in the correct alphabetical order.

> +Facebook Yosemite v3.5 Platform and CraterLake Server (``fby35``)
> +==================================================================
> +
> +Facebook has a series of multi-node compute server designs named
> +Yosemite. The most recent version released was
> +`Yosemite v3 <https://www.opencompute.org/documents/ocp-yosemite-v3-platform-design-specification-1v16-pdf>`__.
> +
> +Yosemite v3.5 is an iteration on this design, and is very similar: there's a
> +baseboard with a BMC, and 4 server slots. The new server board design termed
> +"CraterLake" includes a Bridge IC (BIC), with room for expansion boards to
> +include various compute accelerators (video, inferencing, etc). At the moment,
> +only the first server slot's BIC is included.
> +
> +Yosemite v3.5 is itself a sled which fits into a 40U chassis, and 3 sleds
> +can be fit into a chassis. See `here <https://www.opencompute.org/products/423/wiwynn-yosemite-v3-server>`__
> +for an example.
> +
> +In this generation, the BMC is an AST2600 and each BIC is an AST1030. The BMC
> +runs `OpenBMC <https://github.com/facebook/openbmc>`__, and the BIC runs
> +`OpenBIC <https://github.com/facebook/openbic>`__.
> +
> +Firmware images can be retrieved from the Github releases or built from the
> +source code, see the README's for instructions on that. This image uses the
> +"fby35" machine recipe from OpenBMC, and the "yv35-cl" target from OpenBIC.
> +Some reference images can also be found here:

> +    $ wget https://github.com/peterdelevoryas/OpenBIC/releases/download/oby35-cl-2022.13.01/Y35BCL.elf
> +
> +Since this machine has multiple SoC's, each with their own serial console, the
> +recommended way to run it is to allocate a pseudoterminal for each serial
> +console and let the monitor use stdio. Also, starting in a paused state is
> +useful because it allows you to attach to the pseudoterminals before the boot
> +process starts.

[PATCH 7/7] docs/system/target-arm.rst: Remove "many boards are undocumented" note

[Peter Maydell]

We now have at least placeholder documentation for every Arm board,
so we can remove the apologetic note that says that there are
undocumented ones which you can only find out about via the
``--machine help`` option.
