* change #include "fileio.h" to <helper/fileio.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "fileio.h" the following form should be used. #include <helper/fileio.h> The exception is from .c files in the same directory.
* nand: factor init to 'nand init'Zachary T Welch2009-12-021-0/+26
| | | | | Split NAND initialization into 'nand init', which gets called from the main 'init' command.
* add 'nonce' nand driverZachary T Welch2009-11-281-0/+2
| | | | | The nonce NAND driver provides a no-op implementation useful for testing the system independently of any driver side-effects.
* fix 'nand info' commandZachary T Welch2009-11-271-5/+5
| | | | | | Move device argument parsing after check for number of arguments; otherwise, calling this command without any arguments would access argv[0] before checking whether it even existed.
* remove nand_controller->register_callbacksZachary T Welch2009-11-241-5/+6
| | | | | Replace flash_driver callback with pointer to command_registration. Eliminates all related routines and allows drivers to omit commands.
* nand: use register_commands()Zachary T Welch2009-11-241-47/+98
| | | | Eliminates 'nand_cmd' global variable.
* use COMMAND_REGISTER macroZachary T Welch2009-11-241-12/+12
| | | | | Replaces direct calls to register_command() with a macro, to allow its parameters to be changed and callers updated in phases.
* NAND verify doesn't advance.Dean Glazeski2009-11-191-1/+1
| | | | | | Fix to move the device address up as the contents are verified. Signed-off-by: Zachary T Welch <zw@superlucidity.net>
* add support for naming NAND banksZachary T Welch2009-11-191-3/+10
| | | | | Requires users to name their nand banks, allowing them to be used instead of bank numbers in script commands.
* refactor handle_nand_device_commandZachary T Welch2009-11-191-62/+62
| | | | | | | | | Move bulk of for-loop to a new static command helper function. Adds handle_nand_list_drivers command handler, registered as 'nand drivers'. Improves command help text and error reporting.
* rename flash and nand command helpersZachary T Welch2009-11-191-7/+7
| | | | | | | After adding support for referencing banks by name, renames the COMMAND_HELPERs appropriately: flash_command_get_bank_by_num -> flash_command_get_bank nand_command_get_device_by_num -> flash_command_get_device
* allow flash/nand banks commands to accept namesZachary T Welch2009-11-191-1/+23
| | | | | | | | | | | | | | | | Add get_flash_bank_by_name (and get_nand_device_by_name) helpers to retrieves struct flash_bank * (struct nand_device *) given a driver name and an (optional) driver-specific bank index. These are used to extend flash_command_get_bank_by_num (and nand_command_get_device_by_num) to allow all flash (nand) commands to reference defined banks by name, not just by number. To avoid some code duplication, add the flash/common.[ch] files to hold functionality common to both types driver. The first two methods are helpers for the above routines to find a bank specified by a "name" or "name.index" string. get_flash_name_index() finds the '.index' portion, while flash_driver_name_matches() performs the string portion matching.
* nand_fileio_parse_args parses wrong param for sizeDean Glazeski2009-11-191-1/+1
| | | | | | | This changes the size parameter from argv[2] to argv[3], which is what it's supposed to be. Signed-off-by: Zachary T Welch <zw@superlucidity.net>
* use COMMAND_PARSE_ENABLE macro where appropriateZachary T Welch2009-11-181-8/+1
| | | | | | | | Updates all command parsing of simple "enable" and "disable" arguments. A few case in the tree use a tri-state or extended arguments, which cannot use this simple macro. Simlifies the xscale icache/dcache command handler logic.
* command_handler: change 'cmd_ctx' to CMD_CTXZachary T Welch2009-11-171-33/+33
| | | | Convert all command handler 'cmd_ctx' parameter usage with CMD_CTX.
* command_handler: change 'args' to CMD_ARGVZachary T Welch2009-11-171-28/+28
| | | | | This patch converts all instances of 'args' in COMMAND_HANDLER routines to use CMD_ARGV macro.
* command_handler: change to 'argc' to CMD_ARGCZachary T Welch2009-11-171-12/+12
| | | | | This patch converts all instances of 'argc' in COMMAND_HANDLER routines to use CMD_ARGC.
* fileio: improve API typesZachary T Welch2009-11-161-3/+3
| | | | | | | | | | | | | Use size_t instead of uint32_t when specifying file sizes. Update all consumers up through the layers to use size_t when required. These changes should be safe, but the higher-levels will need to be updated further to receive the intended benefits (i.e. large file support). Add error checking for fileio_read and file_write. Previously, all errors were being silently ignored, so this change might cause some problems for some people in some cases. However, it gives us the chance to handle any errors that do occur at higher-levels, rather than burying our heads in the sand.
* struct fileio: improve member typesZachary T Welch2009-11-161-1/+1
| | | | | | Add const keyword to file url and cast to free(). Make size an ssize_t and chase all format strings that use it.
* nand_command_get_device_by_num: make COMMAND_HELPERZachary T Welch2009-11-161-8/+9
| | | | | Use COMMAND_HELPER macro to define nand_command_get_device_by_num. Use CALL_COMMAND_HANDLER to invoke it.
* 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
