In rST markup, single backticks `like this` represent "interpreted text", which can be handled as a bunch of different things if tagged with a specific "role": https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#interpreted-text (the most common one for us is "reference to a URL, which gets hyperlinked"). The default "role" if none is specified is "title_reference", intended for references to book or article titles, and it renders into the HTML as <cite>...</cite> (usually comes out as italics). This commit fixes various places in the manual which were using single backticks when double backticks (for literal text) were intended, and covers those files where only one or two instances of these errors were made.

Nuvoton iBMC boards (``*-bmc``, ``npcm750-evb``, ``quanta-gsj``)
|
|
================================================================
|
|
|
|
The `Nuvoton iBMC`_ chips (NPCM7xx) are a family of ARM-based SoCs that are
|
|
designed to be used as Baseboard Management Controllers (BMCs) in various
|
|
servers. They all feature one or two ARM Cortex-A9 CPU cores, as well as an
|
|
assortment of peripherals targeted for either Enterprise or Data Center /
|
|
Hyperscale applications. The former is a superset of the latter, so NPCM750 has
|
|
all the peripherals of NPCM730 and more.
|
|
|
|
.. _Nuvoton iBMC: https://www.nuvoton.com/products/cloud-computing/ibmc/
|
|
|
|
The NPCM750 SoC has two Cortex-A9 cores and is targeted for the Enterprise
|
|
segment. The following machines are based on this chip :
|
|
|
|
- ``npcm750-evb`` Nuvoton NPCM750 Evaluation board
|
|
|
|
The NPCM730 SoC has two Cortex-A9 cores and is targeted for Data Center and
|
|
Hyperscale applications. The following machines are based on this chip :
|
|
|
|
- ``quanta-gbs-bmc`` Quanta GBS server BMC
|
|
- ``quanta-gsj`` Quanta GSJ server BMC
|
|
|
|
There are also two more SoCs, NPCM710 and NPCM705, which are single-core
|
|
variants of NPCM750 and NPCM730, respectively. These are currently not
|
|
supported by QEMU.

Boot options
|
|
------------
|
|
|
|
The Nuvoton machines can boot from an OpenBMC firmware image, or directly into
|
|
a kernel using the ``-kernel`` option. OpenBMC images for ``quanta-gsj`` and
|
|
possibly others can be downloaded from the OpenPOWER jenkins :
|
|
|
|
https://openpower.xyz/
|
|
|
|
The firmware image should be attached as an MTD drive. Example :
|
|
|
|
.. code-block:: bash
|
|
|
|
$ qemu-system-arm -machine quanta-gsj -nographic \
|
|
-drive file=image-bmc,if=mtd,bus=0,unit=0,format=raw
|
|
|
|
The default root password for test images is usually ``0penBmc``.
