2010-11-13mtd-utils: nandwrite: Clarify usage of aligned "erasesize"Brian Norris
Due to the presence of the "--block-align" flag, nandwrite uses a blocksize throughout that, depeding on the execution parameters, may not be the actual erasesize of the NAND flash. In order to clarify this situation for the untrained viewer of nandwrite's code, we should not change the value of "meminfo.erasesize" itself; rather, we can utilize a separate, calculated "ebsize_aligned". Then, when a user actually wants to refer to the physical erasesize, it's straightforward.

2010-11-13mtd-utils: nandwrite: Comment, style fixupsBrian Norris
Comment on "blockalign" default value is incorrect; it only defaults to a 1x multiplier of the actual block size. Perhaps this is a relic of early NAND where all block sizes were 16KB? Reformatted a multi-line comment. Changed separete "if" statements to a combined "if-else-if" since they were logically combinable. Should have no effect on results with minor effect on efficiency.

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: flash_erase: Fix output of offsetsBrian Norris
Need to use unsigned arithmetic and a 64-bit cast in order to calculate and output the correct offset for eraseblocks at large offsets. Signed integer arithmetic does not produce the correct result "uint64_t" result, so for offsets over 2GB we get messages like: Erasing 512 Kibyte @ ffffffff83180000 -- 4308642136 % complete. Note that this error was not affecting proper erasure; it just produced incorrect status messages. Also, we should not add an extra eraseblock for the final status message; this gives misleading output when, for example, the following statement is executed: $ flash_erase /dev/mtd0 0 1 Erasing 512 Kibyte @ 80000 -- 100 % complete We aren't erasing at offset 0x80000; it should display offset 0.

2010-10-17mtd-utils: nandwrite: Large page+oob supportBrian Norris
Dynamic allocation of the oob buffer provides the necessary support for removing the oob size check. Now, new unknown OOB sizes can be handled correctly (for example, 8KB page + 448B OOB). Included common.h for the use of xmalloc. Memory freeing should occur on "restoreoob" as well as on "closeall."

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.

2010-10-02libmtd: make malloc failures fatalMike Frysinger
This converts libmtd to the common xalloc helpers and in doing so, makes memory allocation failures fatal rather than returning an error to the caller. I think this is acceptable behavior. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
2010-10-02sumtool/libfec: convert "()" to "(void)" in func defsMike Frysinger

2010-10-01mtd-utils: xalloc: simplify/unify error messagesMike Frysinger
I'm not sure that if we actually are out of memory that declaring the failing allocation size is useful in the output. So use the same simple string in every error message to cut down on size (there will only be one copy of this at runtime). Size is a much more common concern than handling OOM issues which most likely aren't the fault of mtd-utils in the first place.
