Message-Id: <1545381188-514-1-git-send-email-yamada.masahiro@socionext.com>

From: Masahiro Yamada <yamada.masahiro@...ionext.com>

Subject: [PATCH 1/5] kconfig: split some C files out of zconf.y
I want to compile each C file independently instead of including all
of them from zconf.y.
These 4 files are low hanging fruits.
