Doxygen doesn't support incremental builds. It could be ok because it
doesn't take much time in this codebase. However it's not because it
makes old output look new which has a cascade effect on sphinx:
https://sourceforge.net/p/doxygen/mailman/message/36580807/
Make doxygen artificially smarter by saving and restoring modify
timestamps on the filesystem for doxygen output files that haven't
changed.
On my system this brings down the time to run an incremental "make
htmldocs" from 75s down to 8s (cmake -DKCONFIG_TURBO_MODE=1 used in both
cases)
This optimization speeds-up non-doxygen documentation work only.

Building the documentation for all the Kconfig options significantly
adds to the total doc build time. When making and testing major changes
to the documentation, we provide an option to temporarily stub-out
the auto-generated configuration documentation so the doc build process
runs much faster.
To enable this mode, set the following option when invoking cmake
-DKCONFIG_TURBO_MODE=1

In a clean build, Ninja is creating copies of the extracted
documentation outputs regardless of whether they already exist or
not. I can't explain this behavior from the documentation of the build
command, but it's so, even if extract_content.py is patched to use
copyfile() instead of copy2() so that outputs (copied .rst files in
the build directory) have strictly newer mtimes than inputs (source
tree .rst files).
This extra copying doesn't happen for incremental builds, for some
reason.
To account for this behavior, add and use an extract_content.py option
that skips content extraction completely and leaves that all up to the
add_custom_command() which tracks each individual input->output build
command.

The logic which copies source documentation files into the build
directory could use some improvements to its dependency management, so
that when a source file changes, extract_content.py gets re-run.
Make these changes as follows:
- Add an --outputs flag to extract_content.py, so that the
sources it depends on and generates can be saved into a file and
thus made known to the build system
- Change the way the sources and destination are specified in the
extract_content.py command line so that the entire job can be done
in a single command, rather than multiple (to avoid having to
collate multiple --outputs files in CMake)
- Extract the content at configure time with execute_process(),
tracking all inputs and outputs within the build system itself. Use
this information to make sure that each individual output depends on
just its exact input file, ensuring updated inputs produce updated
outputs without having to call extract_content.py again.
- Ensure that the "content" build system target depends on all the
outputs, transitively triggering a rebuild any time an input
file (e.g. .rst documentation file or included image/source file)
changes.

Separate the phases of creating the list of outputs (and output
directories) from the actual creation of these outputs. This lays the
groundwork for just printing the inputs and outputs in a subsequent
patch, enabling CMake to track dependencies properly.
In the now-separate output generation phase, use shutil.copy2() to
preserve metadata like access and modification times when possible,
rather than re-reading every file and seeing if the contents are
different. This has the same semantics but is clearer and potentially
more efficient, as the initial copies have more accurate relative
timestamps.

Minor cleanups:
- Allow the user to run extract.content.py -h with ZEPHYR_BASE unset
without crashing
- Replace the use of the ZEPHYR_BUILD environment variable with an
--ignore argument (that can be given multiple times) which specifies
a path to a directory whose files should *not* be copied, and use
it to ignore the build directory
- rename, reorder, and tweak get_files() arguments a bit to go from
source to dest, with extra configuration at the end, getting rid of
local shadowing of global built-in functions

Update menuconfig (and Kconfiglib, just to sync) to upstream revision
256e5b3e38e92 to get the fix below in, for an issue in an external
project. Also update genrest.py with a similar fix (the genrest issue
was what originally prompted it).
menuconfig: Improve/fix promptless choice handling
The code assumed that all parent (interface) menus always have a
prompt, which is false for items in promptless choices. This led to
a crash e.g. when viewing the symbol information for a symbol within
a promptless choice.
Promptless choices with children can show up "legitimately" when
people define choices in multiple locations to add symbols, though
this is broken in the C tools.
Use standard_sc_expr_str(node.item) instead of the non-existing
prompt for promptless choices. That way they show up as
'<choice (name if any>)>', which is consistent with how they're
shown elsewhere.
This commit also changes how choice names are displayed in
show-name/show-all mode, to the standard_sc_expr_str() format.

This adds new targets to generate build documentation through
LaTEX to PDF.
There are a few notes:
1. pdflatex complains about the tex file generated by doxygen
so it needs to be fixed with a Python script before feeding
in through pdflatex.
2. SVG files are not recognized by pdflatex so they are converted
to known good format on the fly, only for producing PDF. This
uses the libRSVG's rsvg-convert tool.

* All .rst and additional required files are now copied from the doc/

and another into build/doc/rst) to manage relative paths.
* All paths are absolute where possible, including themes and static

It's common for people to put in a 'default n' "just in case", because
it might not be obvious that bool symbols implicitly default to 'n'. To
make it clearer, mention the implicit default value on the reference
pages of symbols without defaults.
Also mention that choices without defaults default to the first
(visible) symbol in the choice.
Note: Adding to the confusion, Kconfig used to generate a
'# CONFIG_FOO is not set' line for 'default n', but no output when there
was no default. I changed that recently in both the C tools and
Kconfiglib. There's no output either case now (unless the symbol is
visible).

The genrest.py script (used to create the Kconfig configuration option
documentation) was depending on the environment's locale settings to

When we reused this script for another project, that environment's

encoding. This patch is a prophylactic measure to prevent potential

Improve error reporting to include the filename being processed when a
problem occurs during a pre-generation phase when boards and samples
files are temporarily copied (by doc/scripts/extract_content.py) into
the documentation area for processing.
Two recent problems were noticed:
Some new files were using window-1252 encoding and included windows
printer quote marks and hyphens, for example 0x92 in window-1252
encoding is Unicode 0x2019 for 'RIGHT SINGLE QUOTATION MARK'.
An image file reference by a reST file was missing
Both of these threw an exception reporting the error, but did not
include any information about the file currently being processed, making
it hard to fix the problem (e.g., change the Windows right quote
character to an ASCII ').

Until now, choices have kinda been a black box in the Kconfig reference,
and hid the dependencies of choice symbols (because choice symbols
depend directly on the choice rather than on whatever the choice
'depends on').
Generate separate information pages for choices and turn <choice>
dependencies into links.
One complication is that choices (usually) don't have names. Use the
index of each choice in the Kconfig files (first choice seen = choice 0,
then choice 1, etc.) instead to identify each choice.
Choice reference pages include the same information as symbol reference
pages (minus some things that don't apply for choices), and also list
the choice symbols contained in the choice.

Sphinx defaults to Python highlighting, but a Kconfig lexer is available
as well
(http://pygments.org/docs/lexers/#pygments.lexers.configs.KconfigLexer).
Use it.
This only highlights Kconfig definitions without links (references to
other symbols), as Sphinx doesn't highlight '.. parsed-literal::' blocks
with links. It's an improvement over Python stuff getting highlighted at
least.
Side note: '.. highlight:: none' still gives '.. parsed-literal::'
blocks without links a different background color, for whatever reason.

Make all menu paths ("(top menu) -> menu -> submenu -> ...") exclude

Previously, implicit submenus were excluded in the menu path at the top

The logic for walking reverse dependencies (from 'select's and 'imply's)
is a bit tricky to read (and write), and was essentially duplicated in a
few different spots (including in the upcoming menuconfig
implementation).
Use a new split_expr() helper function that's been added to Kconfiglib
to reduce code duplication and make the code more readable.

a particular symbol now has the symbols in the order that they appear in

The new version of the reference page for a symbol lists the following
essential and generally useful information at the top of the page:
- Prompt
- Type
- Help text
- Direct dependencies (from 'depends on', and inherited from if's and
menus)
- Defaults
- Other symbols selecting or implying the symbol
The current symbol value and visibility are no longer displayed. They
don't make much sense in a reference document, as they depend on user
values from configuration files.
The bottom of the reference page also includes the symbol represented in
Kconfig format (including propagated dependencies).
All references to defined symbols appearing in expressions are turned
into links, which can be clicked on to jump to the reference page for
that symbol.
The following (slightly outdated) screenshot gives an idea of the
format:
