Add a cleaned-up version of a script I used to find a bunch of unused symbols and some other Kconfig issues. It's set up to be run directly, with few environment dependencies. West is required, because the checks need to see Kconfig files and source code from all modules. Checks so far: - Symbols that can never be anything but n/empty - Symbols that look unused - menuconfig symbols with empty menus - Symbols only defined in Kconfig.defconfig files See the help strings for the command-line flags for more information. Some of these checks could probably be checked in CI later, though the always-n and unused-symbol checks are a bit heuristic and might need a lot of whitelisting. Another reason I want to get this in is to have a clean standalone reference for how to set up the environment for parsing the Kconfig files. It's gotten trickier over time.
