kconfig: Clean up header comments and make them consistent Use this short header style in all Kconfig files: # <description> # <copyright> # <license> ... Also change all <description>s from # Kconfig[.extension] - Foo-related options to just # Foo-related options It's clear enough that it's about Kconfig. The <description> cleanup was done with this command, along with some manual cleanup (big letter at the start, etc.) git ls-files '*Kconfig*' | \ xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /' Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

kconfig: Turn pointless/confusing 'menuconfig's into 'config's Defining a symbol with 'menuconfig' just tells the menuconfig to display any dependent symbols that immediately follow it in a separate menu. 'menuconfig' has no effect on symbol values. Making a symbol that doesn't have any dependent symbols after it a 'menuconfig' should be avoided, because then you end up with an empty menu, which is shown as e.g. [*] Enable foo --- This is how it would be shown if there were children but they all happened to be invisible as well. With a regular 'config', it turns into [*] Enable foo Change all pointless 'menuconfig's to 'config's. See the section on 'menuconfig' on the Kconfig - Tips and Best Practices page as well.
