Sorry, there is no decicated ML for Kconfig. Kconfig patches should go to linux-kbuild ML (linux-kbu...@vger.kernel.org). If you want to subscribe to the list, please visit http://vger.kernel.org/vger-lists.html#linux-kbuild Yann E. MORIN is not active these days, so I think Michal Marek is the maintainer. -- Best Regards Masahiro Yamada _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
