Syncing kconfig files is easy since the files are collected in the single place, scripts/kconfig/. It is true you need some efforts to introduce Kconfig in your project, but once established, it is just a matter of copying files under scripts/kconfig. Copying stuff directly from Linux would be as easy as doing so from your init-kconfig. > This may also be useful if folks want to test R&D code on a smaller > compartamentalized codebase. > > If you find this useful and you'd like to help keep it in sync, send > patches my way as the kernel's kconfig evolves.

Kbuild Skeleton https://github.com/masahir0y/kbuild_skeleton It consists of some core Makefiles and Kconfig. >From the time-stamp, it is already 6 years too old. I am not sure if it is useful for people, if so, it is pretty easy to sync up with the latest Linux. -- Best Regards Masahiro Yamada
