RTT locking is now implemented with spinlocks:
* The prior implementation did not support RTT logging and tracing from
ISR context.
* Mutexes caused infinite loops when tracing.
* Spinlocks are more lightweight than mutexes, especially on non-SMP
systems.
Fixes: #61133

Consistently use
config FOO
bool/int/hex/string "Prompt text"
instead of
config FOO
bool/int/hex/string
prompt "Prompt text"
(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).
The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.
Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some

Up until now, Zephyr has patched Kconfig to use the last 'default' with
a satisfied condition, instead of the first one. I'm not sure why the
patch was added (it predates Kconfiglib), but I suspect it's related to
Kconfig.defconfig files.
There are at least three problems with the patch:
1. It's inconsistent with how Kconfig works in other projects, which
might confuse newcomers.
2. Due to oversights, earlier 'range' properties are still preferred,
as well as earlier 'default' properties on choices.
In addition to being inconsistent, this makes it impossible to
override 'range' properties and choice 'default' properties if the
base definition of the symbol/choice already has 'range'/'default'
properties.
I've seen errors caused by the inconsistency, and I suspect there
are more.
3. A fork of Kconfiglib that adds the patch needs to be maintained.
Get rid of the patch and go back to standard Kconfig behavior, as
follows:
1. Include the Kconfig.defconfig files first instead of last in
Kconfig.zephyr.
2. Include boards/Kconfig and arch/<arch>/Kconfig first instead of
last in arch/Kconfig.
3. Include arch/<arch>/soc/*/Kconfig first instead of last in
arch/<arch>/Kconfig.
4. Swap a few other 'source's to preserve behavior for some scattered
symbols with multiple definitions.
Swap 'source's in some no-op cases too, where it might match the
intent.
5. Reverse the defaults on symbol definitions that have more than one
default.
Skip defaults that are mutually exclusive, e.g. where each default
has an 'if <some board>' condition. They are already safe.
6. Remove the prefer-later-defaults patch from Kconfiglib.
Testing was done with a Python script that lists all Kconfig
symbols/choices with multiple defaults, along with a whitelist of fixed
symbols. The script also verifies that there are no "unreachable"
defaults hidden by defaults without conditions
As an additional test, zephyr/.config was generated before and after the
change for several samples and checked to be identical (after sorting).
This commit includes some default-related cleanups as well:
- Simplify some symbol definitions, e.g. where a default has 'if FOO'
when the symbol already has 'depends on FOO'.
- Remove some redundant 'default ""' for string symbols. This is the
implicit default.
Piggyback fixes for swapped ranges on BT_L2CAP_RX_MTU and
BT_L2CAP_TX_MTU (caused by confusing inconsistency).
Piggyback some fixes for style nits too, e.g. unindented help texts.

Bool symbols implicitly default to 'n'.
A 'default n' could make sense e.g. in a Kconfig.defconfig file, if you
wanted to override a 'default y' on the base definition of the symbol,
but it doesn't seem to be used like that on any of these symbols.

Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build
$ make

ReST defines interpreted text roles where text enclosed by single quotes
can be "intrepreted", for example :ref:`some name` becomes a link to
a label anywhere in the doc set named "some name", :c:func:`funcname()`
becomes a link to the API documentation for "funcname", and
:option:`CONFIG_NAME` becomes a link to, in our case, the documentation
for the generated Kconfig option.
This patch fixes uses of `some name` (without a role) by either adding
an explicit role, or changing to ``some name``, which indicates inline
code block formatting (most likely what was intended).
This is a precursor to changing the default behavior of interpreted
text to treat `some name` as :any:`some name` (as configured in
doc/conf.py), which would attempt to create a link to any available
definition of "some name".
We may not change this default role behavior, but it becomes an option
after the fixes in this patch. In any case, this patch fixes incorrect
uses of single-quoted text (possibly introduced because GitHub's
markdown language uses single-quoted text for inline code formatting).

These libraries allow publishing information to enable system profiling
when using the SEGGER SystemView tool. This tool provides a way to record
and visualize events such as threads scheduling, interrupts, and can help
find unintended interactions and resource conflicts. More information can

platforms.
