* ARM NAND I/O interface updateDean Glazeski2009-12-031-7/+37
| | | | | | | | | | | Modify the arm_nand_data struct to better support both read and write operations while using the same struct. An additional field was added, and initialized, to record the last operation so that the correct code can be loaded to the working area. [dbrownell@users.sourceforge.net: merge init patch, tweak GPL note] Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* change #include "nand.h" to <flash/nand.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "nand.h" the following form should be used. #include <flash/nand.h> The exception is from .c files in the same directory.
* change #include "binarybuffer.h" to <helper/binarybuffer.h>Zachary T Welch2009-12-031-1/+1

* ARM NAND I/O header documentation update.Dean Glazeski2009-11-261-6/+10
| | | | | | | Fixed the header file to properly specify the doxygen documentation for the items defined in it. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM NAND I/O read function.Dean Glazeski2009-11-261-0/+1
| | | | | | | | Implementation of the NAND read function for ARM NAND I/O that includes running a local algorithm on a device to increase the performance of block reads. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* target_t -> struct targetZachary T Welch2009-11-131-1/+1
| | | | Remove misleading typedef and redundant suffix from struct target.
* working_area_t -> struct working_areaZachary T Welch2009-11-131-1/+1
| | | | Remove misleading typedef and redundant suffix from struct working_area.

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
