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 --- rfddump.c | 337 -------------------------------------------------------------- 1 file changed, 337 deletions(-) delete mode 100644 rfddump.c (limited to 'rfddump.c') diff --git a/rfddump.c b/rfddump.c deleted file mode 100644 index 0375bac..0000000 --- a/rfddump.c +++ /dev/null @@ -1,337 +0,0 @@ -/* - * rfddump.c - * - * Copyright (C) 2005 Sean Young - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - */ - -#define PROGRAM_NAME "rfddump" -#define VERSION "$Revision 1.0 $" - -#define _XOPEN_SOURCE 500 /* For pread */ - -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include -#include -#include - -/* next is an array of mapping for each corresponding sector */ -#define RFD_MAGIC 0x9193 -#define HEADER_MAP_OFFSET 3 -#define SECTOR_DELETED 0x0000 -#define SECTOR_ZERO 0xfffe -#define SECTOR_FREE 0xffff - -#define SECTOR_SIZE 512 - -#define SECTORS_PER_TRACK 63 - - -struct rfd { - int block_size; - int block_count; - int header_sectors; - int data_sectors; - int header_size; - uint16_t *header; - int sector_count; - int *sector_map; - const char *mtd_filename; - const char *out_filename; - int verbose; -}; - -void display_help(void) -{ - printf("Usage: %s [OPTIONS] MTD-device filename\n" - "Dumps the contents of a resident flash disk\n" - "\n" - "-h --help display this help and exit\n" - "-V --version output version information and exit\n" - "-v --verbose Be verbose\n" - "-b size --blocksize Block size (defaults to erase unit)\n", - PROGRAM_NAME); - exit(0); -} - -void display_version(void) -{ - printf("%s " VERSION "\n" - "\n" - "This is free software; see the source for copying conditions.
