From 871480933a1c28f8a9fed4c4d34d06c439a7a422 Mon Sep 17 00:00:00 2001 From: Srikant Patnaik Date: Sun, 11 Jan 2015 12:28:04 +0530 Subject: Moved, renamed, and deleted files The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure. --- arch/powerpc/Makefile | 260 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 260 insertions(+) create mode 100644 arch/powerpc/Makefile (limited to 'arch/powerpc/Makefile') diff --git a/arch/powerpc/Makefile b/arch/powerpc/Makefile new file mode 100644 index 00000000..6524c6e2 --- /dev/null +++ b/arch/powerpc/Makefile @@ -0,0 +1,260 @@ +# This file is included by the global makefile so that you can add your own +# architecture-specific flags and dependencies.
