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. --- ANDROID_3.4.5/arch/powerpc/platforms/52xx/efika.c | 238 ---------------------- 1 file changed, 238 deletions(-) delete mode 100644 ANDROID_3.4.5/arch/powerpc/platforms/52xx/efika.c (limited to 'ANDROID_3.4.5/arch/powerpc/platforms/52xx/efika.c') diff --git a/ANDROID_3.4.5/arch/powerpc/platforms/52xx/efika.c b/ANDROID_3.4.5/arch/powerpc/platforms/52xx/efika.c deleted file mode 100644 index 18c10482..00000000 --- a/ANDROID_3.4.5/arch/powerpc/platforms/52xx/efika.c +++ /dev/null @@ -1,238 +0,0 @@ -/* - * Efika 5K2 platform code - * Some code really inspired from the lite5200b platform. - * - * Copyright (C) 2006 bplan GmbH - * - * This file is licensed under the terms of the GNU General Public License - * version 2.
