From 5fe6301a6ddac6b3b74e5d9aae9e28f6f264e799 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 4 Feb 2014 17:24:33 +0900 Subject: [PATCH] kbuild: generate {spl, tpl}-autoconf.mk only when it is necessary Before this commit, {spl,tpl}-autoconf.mk was always generated at the top Makefile even if SPL(TPL) build was not selected. This commit moves the build rule of {spl,tpl}-autoconf.mk from the top Makefile to spl/Makefile. It prevents unnecessary {spl,tpl}-autoconf.mk from being generated.
