The code-block directive requires addition of the prompt symbol for each
line, using the prompt directive instead allows for auto insertion of
the symbol per line[1].
For the readers, the character added by the prompt directive is
un-selectable i.e the entire line can be more easily selected for copy
pasting etc. Whereas with code-block, the prompt symbol like "$" is also
selectable which is usually not the intent.
This is mostly a QoL addition + making the docs consistent since k3.rst
makes use of prompt directives which these board docs include from.

Using some form of sandbox with Python modules is a long standing best
practice with the language. There are a number of ways to have a Python
sandbox be created. At this point in time, it seems the Python community
is moving towards using the "venv" module provided with Python rather
than a separate tool. To match that we make the following changes:
- Refer to a "Python sandbox" rather than virtualenv in comments, etc.
- Install the python3-venv module in our container and not virtualenv.
- In our CI files, invoke "python -m venv" rather than "virtualenv".
- In documentation, tell users to install python3-venv and not
virtualenv.

Jerome Forissier <jerome.forissier@linaro.org> says:
This series introduces threads and uses them to improve the performance
of the USB bus scanning code and to implement background jobs in the
shell via two new commands: 'spawn' and 'wait'.
The threading framework is called 'uthread' and is inspired from the
barebox threads [2]. setjmp() and longjmp() are used to save and
restore contexts, as well as a non-standard extension called initjmp().
This new function is added in several patches, one for each
architecture that supports HAVE_SETJMP. A new symbol is defined:
HAVE_INITJMP. Two tests, one for initjmp() and one for the uthread
scheduling, are added to the lib suite.
After introducing threads and making schedule() and udelay() a thread
re-scheduling point, the USB stack initialization is modified to benefit
from concurrency when UTHREAD is enabled, where uthreads are used in
usb_init() to initialize and scan multiple busses at the same time.
The code was tested on arm64 and arm QEMU with 4 simulated XHCI buses
and some devices. On this platform the USB scan takes 2.2 s instead of
5.6 s. Tested on i.MX93 EVK with two USB hubs, one ethernet adapter and
one webcam on each, "usb start" takes 2.4 s instead of 4.6 s.
Finally, the spawn and wait commands are introduced, allowing the use of
threads from the shell. Tested on the i.MX93 EVK with a spinning HDD
connected to USB1 and the network connected to ENET1. The USB plus DHCP
init sequence "spawn usb start; spawn dhcp; wait" takes 4.5 seconds
instead of 8 seconds for "usb start; dhcp".

Add a new internal API called uthread (Kconfig symbol: UTHREAD) which
provides cooperative multi-tasking. The goal is to be able to improve
the performance of some parts of U-Boot by overlapping lengthy
operations, and also implement background jobs in the U-Boot shell.
Each uthread has its own stack allocated on the heap. The default stack
size is defined by the UTHREAD_STACK_SIZE symbol and is used when
uthread_create() receives zero for the stack_sz argument.
The implementation is based on context-switching via initjmp()/setjmp()/
longjmp() and is inspired from barebox threads [1]. A notion of thread
group helps with dependencies, such as when a thread needs to block
until a number of other threads have returned.
The name "uthread" comes from "user-space threads" because the
scheduling happens with no help from a higher privileged mode, contrary
to more complex models where kernel threads are defined. But the 'u'
may as well stand for 'U-Boot' since the bootloader may actually be
running at any privilege level and the notion of user vs. kernel may
not make much sense in this context.

Add the HAVE_INIJMP symbol to be set by architectures that support
initjmp(), a non-standard extension to setjmp()/longjmp() allowing to
initialize a jump buffer with a function pointer and a stack pointer.
This will be useful to later introduce threads. With this new function
it becomes possible to longjmp() to a particular function pointer
(rather than to a point previously reached during program execution as
is the case with setjmp()), and with a custom stack. Both things are
needed to spin off a new thread. Then the usual setjmp()/longjmp() pair
is enough to save and restore a context, i.e., switch thread.
Add the initjmp() prototype to <include/setjmp.h> since it is common to
all architectures.
Add an entry to the API documentation: doc/api/setjmp.rst.

Qualcomm changes for v2025.07:
CI: https://source.denx.de/u-boot/custodians/u-boot-snapdragon/-/pipelines/25653
There's been a surprising amount of activity lately on the Qualcomm
side with the two oldest boards getting some fresh attention and a lot
of cleanup and polish going on across the board.
* SDM660 gets USB phy fixes and a pinctrl driver
* The recently added SA8775P/QCS9100 SoC gets a pinctrl driver
* The Qualcomm pinctrl driver now handles reserved pins correctly,
fixing crashes on some boards when running "gpio status -a"
* OF_UPSTREAM_BUILD_VENDOR is enabled in qcom_defconfig
* SDM845 and SC7280 get missing clocks added (since we're now stricter
about those). This gets USB working more reliably in more cases.
* DM_USB_GADGET is enabled for all boards using DWC3 and fasbtoot is
enabled too
* A bug in the livetree fixup code is fixed (making USB work on a lot
more platforms)
* Button label lookup is made case insensitive* bootretry becomes more dynamic, allowing it to be hijacked to make a
"persistent" boot menu that allows dropping to U-Boot shell later on
* A new qcom-phone.config fragment is added along with a phone-specific
default environment and phone-specific debugging/bringup docs. These
make U-Boot more usable on devices without a serial port or keyboard.
* The db820c gets fixed up and updated documentation
* The db410c also gets some love and modernisation as well as a new
reviewer.
* A new driver is added for the USB VBUS regulator found on various
Qualcomm PMICs
* The Qualcomm SPMI driver gets some fixes and cleanup for SPMI v5 and
v7 support.
Add some documentation which attempts to describe Qualcomm smartphone
support with the qcom-phone.config fragment, as well as a high level
debugging guide for diagnosing U-Boot issues when UART and framebuffer
are unavailable.
