Ulf Magnusson 4cac371d43 scripts: Suppress/fix undefined variable pylint warnings
dtlib.py and guiconfig.py do some hackery to build token and image
variable names, which triggers spurious pylint warnings like

    scripts/dts/dtlib.py:243:28: E0602: Undefined variable '_T_LABEL'
    (undefined-variable)

Suppress the warning for those files. The generated names get used in
lots of places.

Also suppress some warnings in doc/conf.py ('tags' is from Sphinx), and
fix a legitimate issue in scripts/dts/testdtlib.py.

This pylint check is useful enough to want enabled in the upcoming CI
check.

Håkon Øye Amundsen 208c4ecacb scripts: kconfig: normalize paths to avoid duplicate
There is a bug where non-normalized paths can introduce multiple entries
for the same file. E.g. '/1/2/../2.file' and '/1/2/3/../../2.file' would
both be listed, and end in a ninja error because multiple targets
generate the same file.

This commit fixes this issue by normalizing the paths.

Ulf Magnusson a570b40252 genrest: De-spam docs by skipping direct deps. in more places
Similar deal to commit cc14c40a2d ("kconfiglib: Unclutter symbol
strings, avoid redundant writes, misc.").

Hide the direct dependencies in the defaults, selects, and implies
sections. Do the same in menuconfig/guiconfig as well.

This uses a new Kconfiglib API, so update Kconfiglib to upstream
revision 164ef007a8. This also includes some minor optimizations and
cleanups.

load_config() and write_config() now return a message to print. This

Ulf Magnusson cc14c40a2d kconfiglib: Unclutter symbol strings, avoid redundant writes, misc.
Update kconfiglib, menuconfig, and guiconfig to upstream revision
5c904f4549 to get various improvements and fixes in:

 - Marc Herbert found an issue involving symlinks, absolute paths,
   and rsource that could lead to files not being found. The root cause
   was relpath() assuming that symlink/../bar is the same as bar/, which
   isn't guaranteed.

   Fix it by handling paths in a simpler, more textual way.

 - Propagated dependencies from 'depends on' are now stripped from
   properties when symbols are printed (e.g. in information dialogs and
   generated documentation).

   The printed representation now also uses shorthands.

   Before:

     config A
             bool
             prompt "foo" if C && D
             default A if B && C && D
             depends on C && D

   After:

     config A
             bool "foo"
             default A if B
             depends on C && D

 - Before writing a configuration file or header, Kconfiglib now
   compares the previous contents of the file against the new contents,
   and skips the write if there's no change. This avoids updating the
   modification time, and can save work.

   A message like "No change to '.config'" is shown when there's no
   change.

 - .config now has '# end of <menu>' comments to make it easier to see
   where a menu ends. This was taken from a change to the C tools.

 - load_config() and write_(min_)config() now return a message that can
   be printed with print(kconf.load_config()). This allows messages to
   be reused in e.g. the configuration interfaces (nice now that there's
   also a "No change to..." string).

Ulf Magnusson a1c3cc6660 guiconfig: Add a graphical configuration interface
This is a graphical configuration interface written in Tkinter. Like
menuconfig.py, it supports showing all symbols (with invisible symbols
in red) and jumping directly to symbols. Symbol values can also be
changed directly from the jump-to dialog.

This interface should feel a lot smoother than menuconfig.py on Windows.

When single-menu mode is enabled, a single menu is shown at a time, like
in the terminal menuconfig. Only this mode distinguishes between symbols
defined with 'config' and symbols defined with 'menuconfig'.

Compatible with both Python 2 and Python 3. Has been tested on X11,
Windows, and macOS.

To avoid having to carry around a bunch of GIFs, the image data is
embedded in guiconfig.py. To use separate GIF files instead, change
_USE_EMBEDDED_IMAGES to False. The image files can be found in
https://github.com/ulfalizer/Kconfiglib/tree/screenshots/guiconfig.

Ulf Magnusson 6cfc13522c menuconfig: Small Space/Enter improvement + fix for obscure bug
Update menuconfig (and Kconfiglib, just to sync) to upstream revision
7e0b9f7ae1, to get these commits in:

  menuconfig: Improve space/enter behavior slightly

  Space toggles value is possible, and enters menus otherwise. Enter
  works the other way around.

  Make this explicit in the code, which also fixes some corner cases,
  like space doing nothing on a y-selected menuconfig symbol.

  -------------------------------------------------------------------

  menuconfig: Fix display issue for unsatisfied-deps selected symbol
  with children

  A symbol with unsatisfied direct dependencies can end up with visible
  children in an implicit submenu if it is selected (though that
  generates a warning), so the optimization in _shown_nodes() isn't
  safe, and causes the child nodes to not be shown outside show-all
  mode.

  Just remove the optimization. Trying things out some more,
  everything's plenty fast enough anyway.

  Checking the direct dependencies of the parent instead would be safe.

The menu path now says "(Top)" instead of "(top menu)" too, which is a
bit more compact. Make the same change in genrest.py.

Ulf Magnusson aec74f692c kconfiglib/menuconfig: Various behavior/UI improvements
Update Kconfiglib and menuconfig to upstream revision 90c5573c19, to get
these commits in:

    Warn for unquoted argument to 'source', etc.

    Print a warning suggesting to add quotes for things like

      source foo/bar/Kconfig
      menu title
      prompt unquoted

    Example warning:

      Kconfig:32: warning: style: quotes recommended around
      'lib/Kconfig.debug' in 'source lib/Kconfig.debug'

    That quoteless syntax is supported for compatibility with old
    versions of the C tools. It only works for a single word.

    ==================================================================

    menuconfig: Include all parents in menu paths

    Previously, symbols not defined with 'menuconfig' with children
    weren't listed in the children's menu paths. It was deliberate, but
    it's probably an anti-feature in retrospect, because it can make it
    harder to find stuff by following the menu path.

    Don't try to be clever and just list all the parent nodes in the
    menu path.

    ==================================================================

    menuconfig: Fix display issue for optional-prompt menuconfigs

    _shown_nodes() needs to check whether invisible 'menuconfig' symbols
    with optional prompts have visible children, so that they can be
    shown outside show-all mode. Previously, only 'config' symbols were
    checked.

    ==================================================================

    menuconfig: Remember last saved/loaded path and improve
    _conf_changed

    Remember the last path that was manually saved/loaded instead of
    reverting back to standard_config_filename() (e.g. .config).

    Remember the path to the last saved minimal configuration separately
    as well.

    Also improve the _conf_changed behavior when loading a .config
    within the interface. Instead of always treating it as needing to be
    saved, check if it's outdated, like for the .config file loaded on
    startup.

    Also make the exit message ("No changes to save", etc.) always
    include the target .config file, which is helpful. Previously, only
    the save message did.

Ulf Magnusson a449c98db2 scripts: Fix risky uses of non-raw regex strings in Python scripts
Fixes pylint warnings like this one:

    doc/conf.py:325:0: W1401: Anomalous backslash in string: '\s'.
    String constant might be missing an r prefix.
    (anomalous-backslash-in-string)

The reason for this warning is that backslash escapes are interpreted in
non-raw (non-r-prefixed) strings. For example, '\a' and r'\a' are not
the same string (first one has a single ASCII bell character, second one
has two characters).

It just happens that there's no \s (or \., or \/) escape for example,
and '\s' turns into two characters (as needed for a regex). It's risky
to rely on stuff like that regexes though. Best to make them raw strings
unless they're super trivial.

Also note that '\s' and '\\s' turn into the same string.

Another tip: A literal ' can be put into a string with "blah'blah"
instead of 'blah\'blah'.

Ulf Magnusson 12ba9dfa52 scripts: Remove unused variables in all Python scripts
Discovered with pylint3.

Use the placeholder name '_' for unproblematic unused variables. It's
what I'm used to, and pylint knows not to flag it.

Python tip:

    for i in range(n):
        some_list.append(0)

can be replaced with

    some_list += n*[0]

Similarly, 3*'\t' gives '\t\t\t'.

(Relevant here because pylint flagged the loop index as unused.)

Ulf Magnusson ac059db362 kconfiglib: Give more helpful hints for missing files
Sigvart pointed out that the error message for missing Kconfig files
(which rambles on a lot about $srctree) can easily kick people off in
the wrong direction.

Update Kconfiglib to upstream revision 9f26eb3ae3 to add the following
commit, which makes the error message point to stuff that's more likely
to be the problem:

    Give more helpful error messages when files are missing

    The current error message talks a lot about $srctree, but $srctree
    is seldom the culprit in practice. More common is 'source
    "$(SOME_ENV_VAR)/foo"`, where SOME_ENV_VAR hasn't been set.

    Include the complete 'source ...' line for missing Kconfig files,
    and mention unset environment variables as a hint. Only mention
    $srctree briefly.

    Also shorten the message when a .config can't be a found a bit. This
    message would usually only be seen when working directly with the
    library.

Example error:

    Kconfig:7: '/Kconfig' not found (in 'source
    "$(SOME_ENV_VAR)/Kconfig"'). Check that environment variables are
    set correctly (e.g. $srctree, which is unset or blank). Also note
    that unset environment variables expand to the empty string.

Kumar Gala 87915cd36f dts: stop generating CONFIG_FLASH_LOAD_{OFFSET,SIZE}
As a step to completing removing use of Kconfig defines in dts files we
need to change how we configure/set CONFIG_FLASH_LOAD_{OFFSET,SIZE}.

Previously we would set them based on how the chosen property
'zephyr,code-partition' was set to.  If 'zephyr,code-partition' wasn't
set we would default the values to 0.  We had some generic overlay logic
which would define 'zephyr,code-partition' based on
CONFIG_BOOTLOADER_MCUBOOT.

Going forward if the DTS has 'zephyr,code-partition' set we will
generate DT_CODE_PARTITION_OFFSET & DT_CODE_PARTITION_SIZE defines.  We
will leave it to Kconfig to set CONFIG_FLASH_LOAD_OFFSET &
CONFIG_FLASH_LOAD_SIZE.

We introduce a python script that allows Kconfig to extract data from
the DTS and thus we can utilize DT_CODE_PARTITION_OFFSET and
DT_CODE_PARTITION_SIZE values to set defaults for
CONFIG_FLASH_LOAD_OFFSET & CONFIG_FLASH_LOAD_SIZE.

Ulf Magnusson cf3cddd1cd menuconfig: Prompt for save when Kconfig files change
Update menuconfig and Kconfiglib to upstream revision 16539b4f223fa, to
add the commit below.

    menuconfig: Prompt for save if a different .config would be saved

    Previously, menuconfig.py only prompted for saving the configuration
    if .config didn't exist or the user changed symbol values within the
    interface.

    Also make it prompt for save if Kconfig symbols have been added,
    removed, or have had their defaults changed, provided it would make
    the saved .config differ from the loaded one.

    This usually won't matter for correctness, because loading an
    outdated configuration performs an implicit olddefconfig, but it's
    less confusing.

    Also add a Kconfig.missing_syms attribute that records all
    assignments to undefined symbols in the most recently loaded .config
    file. This is needed to implement the check for whether the saved
    .config would be different.

    As an unrelated change, always prompt for saving if a .config has
    been loaded from within the menuconfig interface. The intention is
    probably often to save the configuration somewhere else, even if it
    isn't modified.

  Save existing configuration to .<filename>.old in write_config()

  Add a default-True 'save_old' flag to write_config(). If 'save_old' is
  True and an existing configuration file is being overwritten, a copy
  of the old configuration file is saved to .<filename>.old (e.g.
  .config.old) in the same directory.

  Errors are ignored, as the old configuration would usually just be a
  nice-to-have, and not essential.

  The same functionality could be added for minimal configuration files
  and headers, but it's probably most useful for configuration files.

Other changes:

  - Parsing performance is improved a bit

  - scripts/kconfig/kconfig.py now prints the path to the merged
    configuration in zephyr/.config, to make it a bit easier to

Ulf Magnusson c1f4d677f2 menuconfig: Improve behavior for named choices included multiple times
Update menuconfig to upstream revision 38dff36b0f97b, to improve the
behavior for a case reported by Øyvind Rønningstad.

Upstream commit message:

    menuconfig: Only list duplicated choice symbols once

    When a Kconfig file defined a named choice and was included multiple
    times, the choice symbols were listed multiple times in the
    menuconfig as well (due to commit 17d7c1e ("menuconfig: Show all
    symbols at each menu location for multi.def. choices")).

    That's probably not what you want. Tweak it so that each symbol is
    only shown once, with the prompt that was used for it at whatever
    choice definition location is entered.

    Also change how the choice selection is displayed before the choice
    is entered, so that the prompt used for the selected symbol at that
    particular location is used. Previously, the prompt at the first
    definition location for the symbol was always used.

 - Display empty menus with '----' instead of '---> (empty)'. This

 - Having two consecutive empty 'if's (which could also appear e.g. due
   to osource) crashed the menuconfig when entering show-all mode, due
   to the 'if' removal logic in Kconfiglib failing to remove one of
   them. All configurations of 'if's are now correctly removed.

   This error was found while reading the code.

Some minor optimizations and some internal cleanup is included as well.

Ulf Magnusson 85f8c0d4eb menuconfig: Add jump-to for choices, menus, and comments
Update menuconfig (and Kconfiglib, just to sync) to upstream revision
bf1701b36634b, to add this commit:

    menuconfig: Add jump-to for choices, menus, and comments

    For choices, search the name and the prompt. This is the same as for
    symbols, except names are optional (and rare) for choices.

    For menus and comments, search the prompt (title text).

    When jumping to a non-empty choice or menu, jump into it instead of
    jumping to its menu node. If show-all mode is off and there are
    visible items in the choice/menu, then jump to the first visible
    node. Otherwise, enable show-all and jump to the first node.

Previously, only symbols could be jumped to.

Various other small fixes/improvements are included too:

 - The "no range constraints" text was dropped from the input dialog
   when settings int/hex symbols without an active 'range'. It might be
   more confusing than helpful.

 - A crash when pressing Ctrl-F (the view-help shortcut) with no matches
   in the jump-to dialog was fixed

 - Some gnome-terminal shoddiness was worked around to remove minor
   jumpiness when reducing the height of the terminal

Ulf Magnusson 5cfe06b6bc genrest/menuconfig: Fix crash for promptless choices
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.

Ulf Magnusson 213a88f7ff Kconfig: Support macro expansion within symbol names
Update Kconfiglib to upstream revision 2be02fac78527 to add support for
expanding macros within symbol names, extending the existing Kconfig
preprocessor
(https://github.com/torvalds/linux/blob/master/Documentation/kbuild/
kconfig-macro-language.txt). Some minor optimizations are included as
well.

This makes it possible to add Kconfig templates to avoid code
repetition, e.g. like below:

Kconfig.log_template:

    choice
    	prompt "Max compiled-in log level for $(module-str)"

    config $(module)_LOG_LEVEL_OFF
    	bool "Off"

    config $(module)_LOG_LEVEL_ERR
    	bool "Error"

    config $(module)_LOG_LEVEL_WRN
    	bool "Warning"

    config $(module)_LOG_LEVEL_INF
    	bool "Info"

    config $(module)_LOG_LEVEL_DBG
    	bool "Debug"

    endchoice

    config $(module)_LOG_LEVEL
    	int
    	default 0 if $(module)_LOG_LEVEL_OFF
    	default 1 if $(module)_LOG_LEVEL_ERR
    	default 2 if $(module)_LOG_LEVEL_WRN
    	default 3 if $(module)_LOG_LEVEL_INF
    	default 4 if $(module)_LOG_LEVEL_DBG

Using the template:

    module = FOO
    module-str = foo
    source "Kconfig.log_template"

    ...

    module = BAR
    module-str = bar
    source "Kconfig.log_template"

This feature might create harder-to-read Kconfig files if abused, so it
should probably be used sparingly.

Ulf Magnusson 9f8d429048 menuconfig: Fix a case of visible symbols not being shown
Update menuconfig (and Kconfiglib, just to sync) to upstream revision
78682a8e3c4fe to get the following fix in, which could cause certain
visible symbols to not show up in the menuconfig interface:

    menuconfig: Always show implicit submenus with visible nodes

    Currently, the symbol BAR below (which ends up indented in an
    implicit submenu) is shown only if DEP is non-n (or if show-all mode
    is enabled):

      config FOO
            bool "foo" if DEP
            default y

      config BAR
            bool "bar" if FOO

    This is bad, because it hides visible symbols from the interface.
    The assumption was that an implicit submenu (which is only created
    if the parent has a prompt) would never have visible items when the
    parent item is invisible, but prompt-specific conditions and
    select/imply can break that assumption.

    Fix it by always showing implicit submenus with visible nodes, along
    with the parent node. If the parent node is invisible, show it in
    red, like in show-all mode (which happens automatically). That's
    probably better than having mysteriously indented nodes when the
    parent is invisible.

(Some other tweaks were made later to avoid showing red outside show-all
mode, because it might look confusing/broken.)

A new color scheme for the menuconfig has been added as well,
contributed by Mitja Horvat (pinkfluid). It can be enabled by setting
the environment variable MENUCONFIG_THEME to 'aquatic'.

The default theme has been tweaked to use bold text for the selected
item too.

Ulf Magnusson d67095ba59 Kconfiglib: Make header symbol order match .config files again
Commit f6bf897780 ("kconfiglib: Add preprocessor and two warnings")
accidentally made the ordering of #define's in generated header files
random (dependent on Python's set() implementation). Minimal
configuration files (which can be saved from the menuconfig) were
affected too.

The intent is for the order to match .config files, which in turn match
symbol definition order. This doesn't affect behavior in any way, but
makes things more readable (and is handier if files are checked in).

Update Kconfiglib to upstream revision a3252f620fad9 to make the
ordering match again. Tests have been added upstream.

Ulf Magnusson 6686efb838 kconfiglib/menuconfig: Add functionality and improve symbol information
Update Kconfiglib and menuconfig to upstream revision 6aea8d06b637e.

Kconfiglib changes:

 - Kconfig files are now looked up just relative to $srctree (if set).
   Previously, each source'd Kconfig file was also looked up in the
   current directory, and Kconfig files there could override Kconfig
   files in $srctree. This is what the C tools do.

   I'm pretty sure that behavior was a bug in the C tools all along, and
   only meant for .config files. It caused problems (and an ugly
   workaround) for the undefined Kconfig symbol CI check in an external
   project.

   The new behavior also saves a bunch of open()'s, though it's probably
   not noticeable.

 - Setting the KCONFIG_STRICT environment variable to 'y' now makes
   Kconfiglib itself warn for references to undefined symbols. This
   isn't safe in general, as some projects use multiple Kconfig trees
   with shared Kconfig files (e.g. the Linux kernel).

   This will be used to simplify the undefined Kconfig symbol CI check.

 - It's now possible to customize how symbols and choices are printed
   within expressions.

   This will be used to make the RST link generation in genrest.py less
   hacky.

 - Instead of having 'gsource', a plain 'source' is now globbing, and
   requires at least one match. There's also 'osource', for when it's
   okay for a glob pattern to match no files.

   'gsource' had the design flaw that there was no way to require at
   least one file to match. I plan on replacing all 'gsource' statements
   with plain 'source's later, but 'gsource' is still supported for
   backwards compatibility.

 - def_int, def_hex, and def_string are now available as a Kconfig
   extensions, analogous to def_bool (set type and add default).

 - Misc. internal cleanup.

menuconfig changes:

 - Boolean value hints are no longer shown to the right of defaults in
   the symbol information for int/hex symbols. Stuff like
   '- 74 (value: "n")' wasn't helpful, and looked confusing.

 - Symbol information has been made more compact in general, e.g. by
   skipping value hints where they aren't helpful
   ('FOO(=y)' instead of 'FOO(=y) (=y)'), and by shortening stuff like
   '(value: "y")' to just '(=y)'.

 - Misc. internal cleanup.

Ulf Magnusson ec3eff57e0 Kconfig: Use the first default with a satisfied condition
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.

Ulf Magnusson 5402662dd9 cmake: kconfig: Fix rerunning cmake after Kconfig warnings
Commit b3d165f ("scripts: kconfig: Handle warnings generated
during evaluation") made it common for kconfig.py to fail after writing
zephyr/.config. This confuses the configuration fragment checksum logic
in cmake/kconfig.cmake, because it expects the saved checksum file to
exist if zephyr/.config exists.

The end result is a CMake error when rerunning the configuration after
non-whitelisted Kconfig warnings.

Fix it by only writing zephyr/.config (and zephyr/include/autoconf.h) in
kconfig.py if there are no warnings-turned-errors.

Also check if the saved checksum file exists in kconfig.cmake before
trying to open it. Normally this shouldn't happen though.

Move the writing of the checksum file to before writing zephyr/.config
as well. That way, zephyr/.config only gets written if the other
operations succeed.
