From 7d81790ced345585b1e647ca9d0f6678e7062fa4 Mon Sep 17 00:00:00 2001 From: Dongsheng Yang Date: Sat, 31 Oct 2015 11:12:01 +0800 Subject: mtd-utils: Restructure the mtd-utils source. * There is no code modification in this commit, only moving * the files to proper place. The user tools looks a little messy as we place almost the all tools in the root directory of mtd-utils. To make it more clear, I propose to introduce the following structure for our source code. mtd-utils/ |-- lib |-- include |-- misc-utils |-- jffsX-utils |-- nand-utils |-- nor-utils |-- ubi-utils |-- ubifs-utils `-- tests Signed-off-by: Dongsheng Yang Signed-off-by: Brian Norris --- mtd_debug.c | 397 ------------------------------------------------------------ 1 file changed, 397 deletions(-) delete mode 100644 mtd_debug.c (limited to 'mtd_debug.c') diff --git a/mtd_debug.c b/mtd_debug.c deleted file mode 100644 index d6993ce..0000000 --- a/mtd_debug.c +++ /dev/null @@ -1,397 +0,0 @@ -/* - * Copyright (c) 2d3D, Inc. - * Written by Abraham vd Merwe - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.
