license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>

This hidden option is set in the board configuration and indicates
the Zephyr release that the board configuration will be removed.
When set, any build for that board will generate a clearly visible
deprecation warning.

Kconfig: Rename $ENV_VAR_{ARCH,BOARD_DIR} to $ARCH/$BOARD_DIR The prefixes might be a leftover from the old 'option env="..."' symbols (which are no longer needed).

# Note: $BOARD_DIR might be a glob pattern
kconfig: Make 'source' non-globbing and use 'gsource' Until now, Zephyr has used a patched Kconfiglib that turns 'source' into a globbing source (by replacing 'source' with 'gsource' at the token level). There's two problems with this: - The patch needs to be maintained separately - Misspelled filenames are silently ignored, as they look like glob patterns that don't match anything Fix it as follows: 1. Replace all 'source' statements that use wildcards with 'gsource' 2. Remove the custom Kconfiglib patch so that 'source' no longer globs The sed pattern '/source.*[*?]/s/source/gsource/' was run over all Kconfig* files to do the replacement. source's that use environment variables that might contain glob patterns were manually changed to gsource. Building the docs in doc/ is a good test, as doc/Makefile deliberately sets the environment variables to glob up as many Kconfig files as possible. Signed-off-by: Ulf Magnusson <ulfalizer@gmail.com>

kconfig: Global whitespace/consistency cleanup Clean up space errors and use a consistent style throughout the Kconfig files. This makes reading the Kconfig files more distraction-free, helps with grepping, and encourages the same style getting copied around everywhere (meaning another pass hopefully won't be needed). Go for the most common style: - Indent properties with a single tab, including for choices. Properties on choices work exactly the same syntactically as properties on symbols, so not sure how the no-indentation thing happened. - Indent help texts with a tab followed by two spaces - Put a space between 'config' and the symbol name, not a tab. This also helps when grepping for definitions. - Do '# A comment' instead of '#A comment' I tweaked Kconfiglib a bit to find most of the stuff. Some help texts were reflowed to 79 columns with 'gq' in Vim as well, though not all, because I was afraid I'd accidentally mess up formatting.

Kconfig: Use new preprocessor syntax for env. variables With the new Kconfig preprocessor (described in https://github.com/torvalds/linux/blob/master/Documentation/kbuild/ kconfig-macro-language.txt), the syntax for expanding environment variables is $(FOO) rather than $FOO. $(FOO) is a general preprocessor variable expansion, which falls back to environment variables if the variable isn't set (like in Make). It can also be used in prompts, 'comment's, etc. The old syntax will probably be supported forever in Kconfiglib for backwards compatibility, but might as well make it consistent now that people might start using the preprocessor more.

# Parse shields references
# Don't do it as a menuconfig, as shield selection is a CMake feature.
kconfig: soc and shield cleanup Always source the Zephyr base soc and shield (board root) Kconfigs directly from Kconfig instead of generated Kconfig files. This has the benefit that it is no longer necessary to generate Kconfig files to source SoC root and shield (board root) when no custom roots are provided. Also this cleans up the doc/CMakeLists.txt and ensures that the doc/CMakeLists.txt is not getting out of sync with the Kconfig.cmake.

Kconfig: Switch to improved globbing statements A design flaw of 'gsource' is that there's no way to require at least one file to match the glob pattern. This could lead to silent errors. Switch to a new design, where a plain 'source' is globbing and requires at least one file to match. A separate 'osource' (optional source) statement is available for cases where it's okay for a pattern (or plain filename) to not match any files. 'orsource' combines 'osource' and 'rsource' (relative source). This commit search-replaces 'gsource' with 'source', but backwards compatibility with 'gsource' is still maintained by making it an alias for 'osource' (and by making 'grsource' an alias for 'orsource'). The three Kconfig files arch/{nios2,posix,xtensa}/Kconfig source arch/{nios2,posix,xtensa}/soc/*/Kconfig, which doesn't match any files. Use 'osource' for those. The soc/*/Kconfig files seem to be for additional SoC-specific symbols, only none exist yet on those ARCHes. Also use 'osource' for the source of $ENV_VAR_BOARD_DIR/Kconfig in boards/Kconfig, which doesn't exist for all boards. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>
