2011-06-25nanddump: default to NOT dumping OOB dataBrian Norris
Since nandwrite doesn't write OOB data by default, we don't dump OOB data by default, in order to be a more proper inverse function. Remove the warnings and change the default. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-06-25nanddump: change -o to mean --oob, not --omitoobBrian Norris
As warned earlier, we are changing the meaning of `nanddump -o' to mirror the usage in nandwrite, where -o means to include OOB (i.e., `nandwrite -o' writes data to both in-band and out-of-band areas, so `nanddump -o' should dump data from both in-band and out-of-band areas).

2011-06-25nanddump: change default to --bb=skipbadBrian Norris
As promised, we change the default bad block handling method to --bb=skipbad. This works as a better inverse to nandwrite, since nandwrite skips bad blocks when writing data. And of course, we remove the warning messages. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2011-06-25nanddump: kill --omitbad, --noskipbadBrian Norris
As mentioned previously, we are killing --omitbad in favor of the new --bb=skipbad option, which functions fairly similarly. Also, --noskipbad has become --bb=dumpbad, so remove the old `-N' and `--noskipbad' flags.

2011-06-23nanddump: document, warn about future default --omitoobBrian Norris
To work as a proper inverse to nandwrite, nanddump must not dump OOB data by default. This patch prints a warning regarding the future change. We also suggest using the new flag, `--oob', for transitioning to the next release with new default behavior. Note that we are changing `-o' to mean `--oob' in the next release, similar to `nandwrite -o'. This is a break from previous behavior. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <dedekind1@gmail.com>
2011-06-23nanddump: add --oob optionBrian Norris
Adds an explicit option for including OOB data in our data dump. Currently, this is the default behavior, but in the next release, the default will be to exclude OOB data. This is done to mirror the '-o' option in nandwrite. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <dedekind1@gmail.com>
2011-06-23nanddump: warn about new default BB handlingBrian Norris
In an upcoming release, we will no longer default to --bb=padbad. Instead, the default will be --bb=skipbad. This makes nanddump a better inverse operation to nandwrite. This patch prints warnings for users so that they get a chance to update their scripts before the default changes officially.

2011-06-23nanddump: update help message for BB method changesBrian Norris
--noskipbad will soon be replaced by --bb=dumpbad, and --omitbad is being removed entirely in favor of --bb=skipbad. This patch adds warnings when using inappropriate configurations and adds info to the help message. Please plan to migrate to the new usages shortly.

2011-06-23nanddump: remove --skipbad, leaving --bb=skipbadBrian Norris
We are moving to unify bad block handling methods under the --bb=METHOD option. Since --skipbad has not been included in a mtd-utils release yet, we can safely replace it without a deprecation and phase-out period. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <dedekind1@gmail.com>
2011-06-23nanddump: add --bb=METHOD optionBrian Norris
We have too many separate bad block handling methods: --omitbad --noskipbad --skipbad On top of these, we have the default option: that bad blocks are replaced with 0xFF. These options will be unified under --bb=METHOD. The end goal will be something like: ---------------------------------------------------------------------------------------------- Old option New option Comment ---------------------------------------------------------------------------------------------- <default> --bb=padbad dump flash data, substituting 0xFF for any bad blocks --noskipbad --bb=dumpbad dump flash data, including any bad blocks --skipbad --bb=skipbad dump good data, completely skipping any bad blocks (new default) --omitbad N/A very similar to `skipbad' (DEPRECTATED) The BB options are all mutually exclusive, so we check that we do not have more than one BB option explicitly enabled on the command line by tracking whether or not a BB method has been set by the user.

2011-06-06nanddump: add --skipbad option for bad blocksBrian Norris
This patch adds a new option "--skipbad" to nanddump. It is subtly different than "--omitbad". The following description was included in the help message to attempt to clarify the differences. Notes on --omitbad and --skipbad: With either option, we stop dumping data when we encounter a bad block and resume dumping at the next good block. However, with --omitbad, we count the bad block as part of the total dump length, whereas with --skipbad, the bad block is 'skipped,' that is, not counted toward the total dump length.

2010-12-02nanddump: change "unsigned" to "signed"Brian Norris
For consistency between nanddump and nandwrite and in order to provide better means for checking for negative inputs, the "offset" and "length" types in nanddump should be changed to signed integer types. This also solves a signed/unsigned comparison warning. Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-12-02nanddump: Refactor pretty print code into an sprintf()Brian Norris
A do-while loop in pretty_dump_to_buffer() can be refactored into a single sprintf() statement. MAX() and MIN() are used to ensure that: (1) We have at least a single space between hex and ASCII output (2) We don't overflow the line buffer This patch was suggested by Mike Frysinger.

2010-12-02nanddump/nandwrite: use "simple_" str functionsBrian Norris
Per Mike Frysinger's suggestion, we check for strtoll() and strtoull() errors by using the "common.h" helper functions simple_strtoll() and simple_strtoull(). Signed-off-by: Brian Norris <computersforpeace@gmail.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-11-13mtd-utils: nanddump: Allow 64-bit lengthsBrian Norris
We should allow the dump length to be 64-bit, especially since the value was read in as a "long long" by strtoll(). Signed-off-by: Brian Norris <computersforpeace@gmail.com> Acked-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-10-25mtd-utils: nanddump: add 64-bit support, utilize libmtdBrian Norris
Adds support for 64-bit offsets (i.e., devices larger than 4GB). Utilizes the "unsigned long long" data type as the standard type for 64-bit offsets throughout. Reformats a few printf statements to avoid casting and to properly handle "long long." Calls to ioctls are mostly replaced by libmtd interfaces (which should choose the proper ioctls for us); however, a few remain and probably should be handled with more robust interfaces, as some of these ioctls are considered "legacy."

2010-10-25mtd-utils: nanddump/nandwrite: style, signed-ness, printing fixupsBrian Norris
There were some signed/unsigned integer comparisons. Their types were changed for safety. Also, "strtol" was improperly used for unsigned data types. Nanddump's pretty print options needed a slight reformat to prepare for printing offsets that are more than 32 bits (8 hex characters) wide. This prevents overlap of output and ensures that at least one space is printed between hex and ascii printouts. Perhaps this could use some better alignment in the future. Other fixes: * Corrected several simple spacing issues * Changed indentation of some global variable declarations in order to prepare for the next patch, which makes those declarations longer * Used macro for PRETTY_ROW_SIZE instead of constant 16 * Reformatted, edited a multi-line comment * Removed some unnecessary casts Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2010-10-18nanddump: warn when the start address is not page alignedBaruch Siach
nanddump should be consistent with nandwrite, which does not accept non page aligned start addresses. Thus, non page aligned dumps are useless. To ease migration only warn for now.

2010-10-17mtd-utils: nanddump: Dynamic buffer, increase pagesize/oobsizeBrian Norris
The buffers used for dumping page and OOB data needed dynamic allocation to help eliminate burdens for updating (i.e., every time there's a new OOB size we don't have to increase the sizes). Also, there is no need to check flash chips for "standard sizes." With recent changes to the printing codebase, we should be able to handle arbitrary sizes with no problem. More exit operations are now necessary on program failure, so "goto closeall" is used more liberally. Also, common.h is included for the use of xmalloc.

2010-09-12nanddump: add --nobad to read bad blocksMike Frysinger

2010-07-21nanddump: add "forcebinary" flagBrian Norris
Restrict binary dumping so that by default, binary garbage is not printed directly to a terminal. Output redicted to files or piped to other commands should not be affected (as judged by "isatty(ofd)"). A new flag "-a" or "--forcebinary" is included so that users can override this behavior if necessary.

2010-07-21nanddump: add canonical (hex+ascii) flagBrian Norris
Added the "-c" or "--canonicalprint" flag (modelled off 'hexdump -C') so that users can choose to print ASCII output next to the prettyprint output.

Adapted code from the linux kernel hex_dump_to_buffer() (lib/hexdump.c) to provide a more robust hexdump for the pretty option. Now, nanddump can print out any size of OOB (or page for that matter...) without having to worry about non-multiples of 16. This also provides ability to dump ASCII format next to the hex output once additional command-line flags are added.

Older kernel do not implement the MTDFILEMODE ioctl. In this case nandwrite and nanddump should have used MEMGETOOBSEL in combination with MEMSETOOBSEL. Unfortunately the return value of the unsucessfull ioctl is not -ENOTTY, but -1 and errno contains ENOTTY. This change fixes this issue. I have not tested all cornercases.
