    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.

    Looks like init-kconfig is trying to build some objects as demo.

    obj-y = main.o
    obj-$(CONFIG_FOO) += foo.o
    obj-$(CONFIG_BAR) += bar.o
    obj-$(CONFIG_BAZ) += baz.o
    obj-$(CONFIG_ALPHA) += alpha/



    FWIW, this is something I played with some time ago.

    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.
