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

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.
