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 --- ftl_check.c | 217 ------------------------------------------------------------ 1 file changed, 217 deletions(-) delete mode 100644 ftl_check.c (limited to 'ftl_check.c') diff --git a/ftl_check.c b/ftl_check.c deleted file mode 100644 index 0eada8f..0000000 --- a/ftl_check.c +++ /dev/null @@ -1,217 +0,0 @@ -/* Ported to MTD system. - * Based on: - */ -/*====================================================================== - - Utility to create an FTL partition in a memory region - - ftl_check.c 1.10 1999/10/25 20:01:35 - - The contents of this file are subject to the Mozilla Public - License Version 1.1 (the "License"); you may not use this file - except in compliance with the License.
