* Add 'nand verify' commandZachary T Welch2009-11-161-0/+65
| | | | | | | | | | | Add the 'nand verify' command to perform a dump and fake-write simultaneously, checking the read bits against those generated by the write process. Appropriate user documentation for this command has been added to the user guide as well. The algorithm presently makes a relatively naive comparison. Some chips that use ECC may not verify correctly using this implementation, but the new documentation provides details about this limitation.
* Use nand_fileio_* in write/dump commands.Zachary T Welch2009-11-161-248/+46
| | | | | | | | | | | This patch eliminates duplicated code in the the NAND 'dump' and 'write' by using the new static helper functions. These changes also fix a possible memory leak in nand dump command, in the case that the dump file failed to open. Overall, the changes should be functionally equivalent, but the resulting code will be easier to improve and extend further.
* Add nand_fileio_* helper APIs.Zachary T Welch2009-11-161-0/+216
| | | | | | | | | | | | | | | This patch provides helpers APIs that will eliminate duplicated code in the the NAND 'dump' and 'write' commands by factoring their common code into static helper functions. These helpers may be useful for creating new commands, as shown in the final patch to 'verify' flash from a file. Several previously unreported error conditions now generate messages and propogate the return codes, such as when the file fails to open and bad arguments are given. These changes will fix a possible memory leak in nand dump command, in the case that the dump file failed to open. Overall, the changes should be functionally equivalent, but the resulting code will be easier to improve and extend consistently.
* command_t -> struct commandZachary T Welch2009-11-131-1/+1
| | | | Remove misleading typedef and redundant suffix from struct command.
* command_context_t -> struct command_contextZachary T Welch2009-11-131-3/+3
| | | | Remove misleading typedef and redundant suffix from struct command_context.
* nand_device_t -> struct nand_deviceZachary T Welch2009-11-131-28/+28
| | | | Remove misleading typedef and redundant suffix from struct nand_device.
* nand_block_t -> struct nand_blockZachary T Welch2009-11-131-1/+1
| | | | Remove misleading typedef and redundant suffix from struct nand_block.
* nand_info_t -> struct nand_infoZachary T Welch2009-11-131-1/+1
| | | | Remove misleading typedef and redundant suffix from struct nand_info.
* nand_manufacturer_t -> struct nand_manufacturerZachary T Welch2009-11-131-1/+1
| | | | Remove misleading typedef and redundant suffix from struct nand_manufacturer.
* nand_ecclayout_t -> struct nand_ecclayoutZachary T Welch2009-11-131-3/+3
| | | | Remove misleading typedef and redundant suffix from struct nand_ecclayout.
* nand_flash_controller_t -> struct nand_flash_controllerZachary T Welch2009-11-131-12/+12
| | | | Remove misleading typedef and redundant suffix from struct nand_flash_controller.
* fileio_t -> struct fileioZachary T Welch2009-11-131-2/+2
| | | | Remove useless structure typedef.
* command_handler_t: make argc unsignedZachary T Welch2009-11-131-4/+2
| | | | | | The number of command arguments will always be 0 or more, so use the right type in handlers. This has a cascading effect up through the layers, but the new COMMAND_HANDLER macros prevented total chaos.
* use CALL_COMMAND_HANDLER instead of direct callsZachary T Welch2009-11-131-1/+2
| | | | | | By using CALL_COMMAND_HANDLER, parameters can be reordered, added, or even removed in inherited signatures, without requiring revisiting all of the various call sites.
* use COMMAND_HANDLER macro to define all commandsZachary T Welch2009-11-131-9/+9
|
* nand: rename device to nandZachary T Welch2009-11-121-213/+213
| | | | | | | To be more informative (and consistent with flash and pld trees), change 'device' parameter name to 'nand' in NAND source files. This change eliminates confusing 'device->device->' instance from the code, and it simplifies the forthcoming command handler patches.
* add const keyword to some APIsZachary T Welch2009-11-111-1/+1
| | | | | | Add 'const' keyword to 'char *' parameters to allow command handlers to pass constant string arguments. These changes allow the 'args' command handler to be changed to 'const' in a subsequent patch.
* flash/*nand*.c: remove useless declarationsZachary T Welch2009-11-091-37/+37
| | | | | | | | Remove useless forward declarations. Moves command registration to end of files. Moves flash structure definition to end of files. Signed-off-by: Zachary T Welch <zw@superlucidity.net>
* Overhaul time support APIZachary T Welch2009-11-091-15/+17
| | | | | | | | | | | | | | | | | | | This patch changes the duration_* API in several ways. First, it updates the API to use better names. Second, string formatting has been removed from the API (with its associated malloc). Finally, a new function added to convert the time into seconds, which can be used (or formatted) by the caller. This eliminates hidden calls to malloc that require associated calls to free(). This patch also removes the useless extern keyword from prototypes, and it eliminates the duration_t typedef (use 'struct duration'). These API also allows proper error checking, as it is possible for gettimeofday to fail in certain circumstances. The consumers have all been chased to use this new API as well, as there were relatively few cases doing this type of measurement. In most cases, the code performs additional checks for errors, but the calling code looks much cleaner in every case.
* Simplify nand indentation.Zachary T Welch2009-11-061-314/+287
| | | | | Removes check covered by new nand_command_get_device_by_num helper. Reverses logic of probe check to further reduce indentation.
* Improve nand.c command argument parsing.Zachary T Welch2009-11-051-72/+53
|
* Add Flash/NAND bank command argument helpers.Zachary T Welch2009-11-051-0/+13
| | | | | | | | This eliminates redundant code for parsing and retreiving the bank specified from a script command argument. This patch was written to replace existing functionality; however, the parsing logic can be updated later to allow flash commands to accept bank names as well as their numbers.
* Minor fixes to NAND code and docsdbrownell2009-09-171-25/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | Erase logic: - command invocation + treat "nand erase N" (no offset/length) as "erase whole chip N" + catch a few more bogus parameter cases, like length == 0 (sigh) - nand_erase() should be static - on error + say which block failed, and if it was a bad block + don't give up after the first error; try to erase the rest - on success, say which nand device was erased (name isn't unique) Device list ("nand list"): - say how many blocks there are - split summary into two lines - give example in the docs Doc tweaks: - Use @option{...} for DaVinci's supported hardware ECC options For the record, I've observed that _sometimes_ erasing bad blocks causes failure reports, and that manufacturer bad block markers aren't always erasable (even when erasing their blocks doesn't trigger an error report). git-svn-id: svn://svn.berlios.de/openocd/trunk@2724 b42882b7-edfa-0310-969c-e2dbd0fdcd60

* David Brownell <david-b@pacbell.net>:zwelch2009-05-241-34/+75
| | | | | | | | | | | | | | | | | | | | | | | | | Update two oddball NAND commands to work with {offset, length} instead of block numbers, matching the other commands as well as usage in U-Boot and the Linux-MTD utilities. Document them accordingly. Update the single in-tree use of those commands (sheevaplug). ALSO: (a) Document the current 2 GByte/chip ceiling for NAND chipsize. (32 bit offset/length values can't represent 4 GBytes.) Maybe after the upcoming release, the code can switch to 64-bits. (b) The "nand check_bad_blocks" should report "bad" blocks. They are not "invalid" blocks; they're "bad" ones. (c) Tweak the "nand info" command to handle the "no arguments" case sanely (show everything, instead of showing garbage) and not listing the blocksize in hex kbytes (duh). git-svn-id: svn://svn.berlios.de/openocd/trunk@1904 b42882b7-edfa-0310-969c-e2dbd0fdcd60
* David Brownell <david-b@pacbell.net>:zwelch2009-05-241-0/+2
| | | | | | | | | | | | | | | | | | NAND support for DaVinci-family drivers, with HW ECC support. Declare the NAND chip on the DM355 EVM board. Currently tested on DM355 for Linux interop using the standard large page (2KB) chip in the EVM socket; "hwecc1" and "hwecc4" work fine. (Using hwecc4 relies on patches that haven't quite made it through the Linux-MTD bottlenecks yet.) Not yet tested: 1-bit on small-page (although it's hard to see how that could fail); 4-bit on small page (picky layout issues); the "hwecc_infix" mode (primarily for older boot ROMs; testing there is blocked on having new bootloader code). git-svn-id: svn://svn.berlios.de/openocd/trunk@1903 b42882b7-edfa-0310-969c-e2dbd0fdcd60

| | | | | | | | | | | | | | | | | Remove un-implemented and dubious "nand copy" command. Doing this efficiently would mean doing the copying on the target CPU, instead of back and forth through JTAG. If anyone ever needs this functionality, that's what they should implement. Also, update on-line "help" for "nand dump" to display its two optional flags; and for "nand write" to display a recently added flag. git-svn-id: svn://svn.berlios.de/openocd/trunk@1883 b42882b7-edfa-0310-969c-e2dbd0fdcd60
