* Make ARM NAND I/O operations aware of last opDean Glazeski2009-12-031-4/+13
| | | | | | | | | Updates the ARM NAND I/O code to look at and update the op field of arm_nand_data to reflect the last operation performed. It uses this field to copy the correct code to the target in the case where the struct is used for reads and writes. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* change #include "armv4_5.h" to <target/armv4_5.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "armv4_5.h" the following form should be used. #include <target/armv4_5.h> The exception is from .c files in the same directory.
* change #include "algorithm.h" to <target/algorithm.h>Zachary T Welch2009-12-031-1/+1

* ARM NAND I/O documentation update.Dean Glazeski2009-11-261-1/+7
| | | | | | | This updates the functions in the file to all have doxygen comments describing what they do. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM NAND I/O refactor code copying.Dean Glazeski2009-11-261-40/+47
| | | | | | | | Created a function for copying code to the working area on a target. The NAND write and read functions are updated to include use of this function. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* ARM NAND I/O read function.Dean Glazeski2009-11-261-1/+90
| | | | | | | | 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: don't implicitly include "algorithm.h"David Brownell2009-11-161-2/+3
| | | | | | | | | | | | | | Most files in the tree seem to have ended up including this, and *quite* needlessly ... only code implementing or using downloadable algorithms actually needs these declarations. So take it out of the header files which included it, and put it in files which use it ... reduce needless interdependencies. Also: "algorithm.h" doesn't need to include "types.h" again; it already comes from a different header. 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.
* armv4_5_common_t -> struct armZachary T Welch2009-11-131-1/+1
| | | | Remove misleading typedef and just use struct arm.
* armv4_5_algorithm_t -> struct armv4_5_algorithmZachary T Welch2009-11-131-1/+1
| | | | Remove misleading typedef and redundant suffix from struct armv4_5_algorithm.
* reg_param_t -> struct reg_paramZachary T Welch2009-11-131-1/+1
| | | | Remove misleading typedef and redundant suffix from struct reg_param.
* David Brownell <david-b@pacbell.net> oharboe2009-09-091-4/+7
| | | | | | | | | | | | | | | | | Optionally shave time off the armv4_5 run_algorithm() code: let them terminate using software breakpoints, avoiding roundtrips to manage hardware ones. Enable this by using BKPT to terminate execution instead of "branch to here" loops. Then pass zero as the exit address, except when running on an ARMv4 core. ARM7TDMI, ARM9TDMI, and derived cores now set a flag saying they're ARMv4. Use that mechanism in arm_nandwrite(), for about 3% speedup on a DaVinci ARM926 core; not huge, but it helps. Some other algorithms could use this too (mostly flavors of flash operation). git-svn-id: svn://svn.berlios.de/openocd/trunk@2680 b42882b7-edfa-0310-969c-e2dbd0fdcd60

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
