From 4d713be1397ed03b405ad37830208d5ab21268cb Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sun, 5 Jul 2015 01:56:57 +0900 Subject: [PATCH] kbuild: use relative path more to include Makefile Prior to this commit, it was impossible to use relative path to include Makefiles from the top level Makefile because the option "--include-dir=$(srctree)" becomes effective when Make enters into sub Makefiles. To use relative path in any places, this commit moves the option above the "sub-make" target. This was imported from Linux (commit a436bb7b8063) and adjusted for U-Boot.
