kconfig: untangle ordering and dependencies There are two major issues with the kconfig: () Some of the config options have incorrect dependencies inside help under menuconfig. For example, CONFIG_GPIO depends on BOARD_GALILEO. () Since the SoC and board specific kconfig files are parsed first, the help screen would say, for example, CONFIG_SPI is defined at arch/arm/soc/fsl_frdm_k64f/Kconfig. This is incorrect because the actual config is defined in drivers/spi/Kconfig. These cause great confusion to users of menuconfig/xconfig. To fix these, the SoC and board defaults are now to be parsed last. Note that the position swapping of defaults in this patch is due to the fact the the default parsed last will be used. And, spi_test is broken due to the fact that it requires CONFIG_SPI_INTEL_PORT_1, but never enables it anywhere. This is bypassed for now.

license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

kconfig: Prune kconfig files that don't match the ARCH or BOARD When Kconfiglib was introduced it caused a significant performance issue. This patch uses pruning to mitigate the performance issue. The pruning exploits the fact that before the Kconfig database is parsed we already know what ARCH and BOARD has been selected. So in theory we could prune away all Kconfig sources that are not related to the current ARCH or BOARD. In practice, it is only the Kconfig sources in zephyr/arch/$ARCH and zephyr/board/$ARCH/ that are easy to prune. Still, that is quite a few Kconfig sources. For qemu_x86 this patch reduced the number of parsed Kconfig source files from 632 to 272. This pruning resulted in a incremental reconfiguration (time cmake ..) speedup of 21% (0.56s to 0.46) and a clean build speedup of 4% (Using board qemu_x86 and sample hello_world). Furthermore, it should be easier to maintain ARCH's and BOARD's out-of-tree since the user now has a mechanism to redirect where Kconfig sources are found. But this has not been explored.

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: Get rid of 'option env' bounce symbols This commit gets rid of the 'option env="ENV_VAR"' bounce symbols. "$FOO" now expands directly to the value of the environment variable FOO, instead of to the value of the Kconfig symbol FOO. This change is likely to soon appear in the C tools as well. Those 'option env' symbols always seemed kinda pointless, and have broken dependency handling due to forcing symbol evaluation during parsing, before all the symbols have even been seen. Compatibility with the C tools could be retained by naming all 'option env' symbols the same as the environment variable they reference. This commit also updated the Zephyr documentation to explain the new behavior. It's relevant for $ZEPHYR_BASE and out-of-tree Kconfig extensions. Commit message from Kconfiglib (cbf32e29a130d) ============================================== Make "$FOO" directly reference the environment variable $FOO in e.g. 'source' statements, instead of the symbol FOO. Use os.path.expandvars() to expand strings (which preserves "$FOO" as-is if no environment variable FOO exists). This gets rid of the 'option env' "bounce" symbols, which are mostly just spam and are buggy in the C tools (dependencies aren't always respected, due to parsing and evaluation getting mixed up). The same change will probably appear soon in the C tools as well. Keep accepting 'option env' to preserve some backwards compatibility, but ignore it when expanding strings. For compatibility with the C tools, bounce symbols will need to be named the same as the environment variables they reference (which is the case for the Linux kernel). This is a compatibility break, so the major version will be bumped to 6 at the next release. The main motivation for adding this now is to allow recording properties on each MenuNode in a clean way. 'option env' symbols interact badly with delayed dependency propagation. Side note: I have a feeling that recording environment variable values might be redundant to trigger rebuilds if sync_deps() is run at each compile. It should detect all changes to symbol values due to environment variables changing value. Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>
