| | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | previous nonfunctional cortex_a8 code with something that at least basically works (for halt/step/resume, without MMU) even if it is incomplete. (With tweaks from Øyvind, and cleanup from Dave.) This code has mainly been developed and tested against R1606, it has been built and tested against R2294 where it runs but step and resume commands are broken due to regression (which should be fixed now). This code is really written for OMAP3530. It doesn't identify debug resources using generic DAP calls to scan the ROM table, or perform topology detection. The OMAP3530 DAP exposes two memory access ports: - Port #0 is connected to L3 interconnect (the main bus) with passthrough to the L4 EMU bus ... so it will be used for most memory accesses. - Port #1 is connected to a dedicated debug bus (L4 EMU), with access to L4 Wakeup, and holds the ROM table ... so it must be used for most debug and control operations. The are some defines to handle this in cortex_a8.c, which should be replaced with more general code. Having access to another Cortex-A8 implementation would help get that right. git-svn-id: svn://svn.berlios.de/openocd/trunk@2609 b42882b7-edfa-0310-969c-e2dbd0fdcd60
* David Brownell Subset of Cortex-A8 support from Magnus: create an armv7a fileoharboe2009-08-253-0/+479
| | | | | | | | | | | | | | | | | | | and seed it with DAP access support using the current ADIv5 code. (With tweaks and cleanup from Øyvind and Dave.) The ARMv7-AR architecture manual is not publicly available (even in subset form like the ARMv7-M spec), so it's hard to distinguish between the Cortex-A8 implementation and the ARMv7-A architecture. The register set presumably is architectural, and so it's stored here; it's like earlier ARMs, with small additions. Ditto the instruction set, though Thumb2 support is used (extending Thumb support from ARMv6 with more 32-bit instructions) and there's this ThumbEE thing too. There is a new "debug monitor" mode, not yet fully addressed here, to support debugging in environments (like motor control) where halting debug mode is inadvisable. git-svn-id: svn://svn.berlios.de/openocd/trunk@2608 b42882b7-edfa-0310-969c-e2dbd0fdcd60
