2009-11-24remove nand_controller->register_callbacksZachary T Welch
Replace flash_driver callback with pointer to command_registration. Eliminates all related routines and allows drivers to omit commands.
2009-11-17command_handler: change 'args' to CMD_ARGVZachary T Welch
This patch converts all instances of 'args' in COMMAND_HANDLER routines to use CMD_ARGV macro.
2009-11-17command_handler: change to 'argc' to CMD_ARGCZachary T Welch
This patch converts all instances of 'argc' in COMMAND_HANDLER routines to use CMD_ARGC.
2009-11-13command_context_t -> struct command_contextZachary T Welch
Remove misleading typedef and redundant suffix from struct command_context.
2009-11-13nand_device_t -> struct nand_deviceZachary T Welch
Remove misleading typedef and redundant suffix from struct nand_device.
2009-11-13target_t -> struct targetZachary T Welch
Remove misleading typedef and redundant suffix from struct target.
2009-11-13nand_flash_controller_t -> struct nand_flash_controllerZachary T Welch
Remove misleading typedef and redundant suffix from struct nand_flash_controller.
2009-11-13nand: add NAND_DEVICE_COMMAND_HANDLER macroZachary T Welch
Abstracts the extended NAND command handling to allow the function signature to be controlled by __COMMAND_HANDLER.
2009-11-11change argv to args in command handlersZachary T Welch
Subsequent patches expect all command handlers to use a uniform parameter naming scheme. In the entire tree, these two files used standard 'argv' instead of our non-standard 'args'. This patch opts to reduces the noise required to unify the command handlers, using dominant 'args' form. A future patch may be used to convert us back to the standard argv, but that requires coordination with all developers to minimize disruptions.

Abstract the orion_nand_fast_block_write() routine into a separate routine -- arm_nandwrite() -- so that other ARM cores can reuse it. Have davinci_nand do so. This faster than byte-at-a-time ops by a factor of three (!), even given the slowish interactions to support hardware ECC (1-bit flavor in that test) each 512 bytes; those could be read more efficiently by on-chip code. NOTE that until there's a generic "ARM algorithm" structure, this can't work on newer ARMv6 (like ARM1136) or ARMv7A (like Cortex-A8) cores, though the downloaded code itself would work just fine there. git-svn-id: svn://svn.berlios.de/openocd/trunk@2663 b42882b7-edfa-0310-969c-e2dbd0fdcd60
2009-08-30David Brownell <david-b@pacbell.net> Minor code bugfix: check right variable.oharboe
Via code review by Steve Grubb <sgrubb@redhat.com>  Almost innocuous; this is value is checked later, this check being wrong would make it check stack garbage. git-svn-id: svn://svn.berlios.de/openocd/trunk@2655 b42882b7-edfa-0310-969c-e2dbd0fdcd60
2009-08-18Piotr Ziecik <kosmo@semihalf.com> Due to errors in chipselect management in ↵oharboe
davinci_nand driver OpenOCD was able to access only to chips attached to first EMIF chipselect. This patch fixes chipselect management code and allows OpenOCD to access to NAND devices attached to any EMIF CS line. git-svn-id: svn://svn.berlios.de/openocd/trunk@2585 b42882b7-edfa-0310-969c-e2dbd0fdcd60

2009-05-24David Brownell <david-b@pacbell.net>: minor davinci_nand bugfixzwelch
Fix a bug that joined us at the last minute, when an efficient alloca() call got swapped out for a more portable malloc(). Also log one error, to give a clue in case it appears "in the wild". git-svn-id: svn://svn.berlios.de/openocd/trunk@1907 b42882b7-edfa-0310-969c-e2dbd0fdcd60

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
