Recommonmark has been deprecated since 2021 [1] and the last release was
over 3 years ago [2]. As per their announcement, Markedly Structured
Text (MyST) Parser [3] is the recommended replacement.
For the most part, the existing documentation is compatible with MyST,
as both parsers are built around the CommonMark flavor of Markdown. The
main difference that affects coreboot is how the Sphinx toctree is
generated. Recommonmark has a feature called auto_toc_tree, which
converts single level lists of references into a toctree:
* [Part 1: Starting from scratch](part1.md)
* [Part 2: Submitting a patch to coreboot.org](part2.md)
* [Part 3: Writing unit tests](part3.md)
* [Managing local additions](managing_local_additions.md)
* [Flashing firmware](flashing_firmware/index.md)
MyST Parser does not provide a replacement for this feature, meaning the
toctree must be defined manually. This is done using MyST's syntax for
Sphinx directives:
```{toctree}
:maxdepth: 1
Part 1: Starting from scratch <part1.md>
Part 2: Submitting a patch to coreboot.org <part2.md>
Part 3: Writing unit tests <part3.md>
Managing local additions <managing_local_additions.md>
Flashing firmware <flashing_firmware/index.md>
```
Internally, auto_toc_tree essentially converts lists of references into
the Sphinx toctree structure that the MyST syntax above more directly
represents.
The toctrees were converted to the MyST syntax using the following
command and Python script:
`find ./ -iname "*.md" | xargs -n 1 python conv_toctree.py`
```
import re
import sys
in_list = False
f = open(sys.argv[1])
lines = f.readlines()
f.close()
with open(sys.argv[1], "w") as f:
for line in lines:
match = re.match(r"^[-*+] \[(.*)\]\((.*)\)$", line)
if match is not None:
if not in_list:
in_list = True
f.write("```{toctree}\n")
f.write(":maxdepth: 1\n\n")
f.write(match.group(1) + " <" + match.group(2) + ">\n")
else:
if in_list:
f.write("```\n")
f.write(line)
in_list = False
if in_list:
f.write("```\n")
```
While this does add a little more work for creating the toctree, this
does give more control over exactly what goes into the toctree. For
instance, lists of links to external resources currently end up in the
toctree, but we may want to limit it to pages within coreboot.
This change does break rendering and navigation of the documentation in
applications that can render Markdown, such as Okular, Gitiles, or the
GitHub mirror. Assuming the docs are mainly intended to be viewed after
being rendered to doc.coreboot.org, this is probably not an issue in
practice.
Another difference is that MyST natively supports Markdown tables,
whereas with Recommonmark, tables had to be written in embedded rST [4].
However, MyST also supports embedded rST, so the existing tables can be
easily converted as the syntax is nearly identical.
These were converted using
`find ./ -iname "*.md" | xargs -n 1 sed -i "s/eval_rst/{eval-rst}/"`
Makefile.sphinx and conf.py were regenerated from scratch by running
`sphinx-quickstart` using the updated version of Sphinx, which removes a
lot of old commented out boilerplate. Any relevant changes coreboot had
made on top of the previous autogenerated versions of these files were
ported over to the newly generated file.
From some initial testing the generated webpages appear and function
identically to the existing documentation built with Recommonmark.
TEST: `make -C util/docker docker-build-docs` builds the documentation
successfully and the generated output renders properly when viewed in
a web browser.

Portwell PQ7-M107
This page describes how to run coreboot on the Portwell PQ7-M107.
PQ7-M107 are assembled with different onboard memory modules: Rev 1.0 Onboard Samsung K4B8G1646D-MYKO memory Rev 1.1 and 1.2 Onboard Micron MT41K512M16HA-125A memory Rev 1.3 Onboard Kingston B5116ECMDXGGB memory
Use 'make menuconfig' to configure onboard memory manufacturer in Mainboard
menu.
Required blobs
This board currently requires: fsp blob 3rdparty/fsp/BraswellFspBinPkg/FspBin/BSWFSP.fd Microcode 3rdparty/intel-microcode/intel-ucode/06-4c-04
Flashing coreboot
Internal programming
The main SPI flash can be accessed using flashrom.
External programming
The system has an internal flash chip which is a 8 MiB soldered SOIC-8 chip. This chip is located on the top middle side of the board. It's located between SoC and Q7 connector. Use clip (or solder wires) to program the chip. Specifically, it's a Winbond W25Q64FW (1.8V), whose datasheet can be found here.
Known issues
- The PQ7 module contains Q7 connector only. Depending on the carrier serial/video/pcie ports might be available.
Untested
- hardware monitor
- SDIO
- Full Embedded Controller support
Working (using carrier)
- USB
- Gigabit Ethernet
- integrated graphics
- flashrom
- external graphics
- PCIe
- eMMC
- SATA
- serial port
- SMBus
- HDA (codec on carrier)
- initialization with FSP MR2
- SeaBIOS payload (version rel-1.11.0-44-g7961917)
- Embedded Linux (Ubuntu 4.15+)
