From: Masahiro Yamada Date: Tue, 4 Feb 2014 08:24:26 +0000 (+0900) Subject: Makefile: rename scripts/Makefile.build to scripts/Makefile.build.tmp X-Git-Tag: v2014.04-rc1~33 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=ec626f11392ca1bc5e83199ceb74e41f0d9ea0c3;p=oweals%2Fu-boot.git Makefile: rename scripts/Makefile.build to scripts/Makefile.build.tmp Some build scripts including scripts/Makefile.build will be imported from Linux Kernel in the next commit. We need to adjust them for U-Boot in the following commits. To make it easier for reviewers to track the modification, this commit renames scripts/Makefile.build to scripts/Makefile.build.tmp beforehand.
