* NOR: add FIXMEs for writing onesDavid Brownell2010-01-081-0/+6
| | | | | | | | It can invalidate ECC codes, and in general is not guaranteed to work. (However on some chips it _appears_ to behave.) Just don't do it; don't write in those cases. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
* whitespace cleanup, mostly for docsAntonio Borneo2009-12-301-7/+7
| | | | | | | | Remove useless space/tab at end of lines. Remove spaces in indentation and replace with tab. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* ARM11: use standard single step simulationDavid Brownell2009-11-241-2/+1
| | | | | | | | | | | | | | | | | | The previous stuff was needed because the ARM11 code wasn't using the standard ARM base type and register access ... but now those mechanisms work, so we can switch out that special-purpose glue. This should resolve all the "FIXME -- handle Thumb single stepping" comments too, and properly handle the processor's mode. (Modulo the issue that this code doesn't yet handle two-byte breakpoints.) Clarify the comments about the the hardware single stepping. When we eventually share breakpoint code with Cortex-A8, we can just make that be the default on cores which support it. We may still want an override command, not just to facilitate testing but to cope with "instruction address mismatch" not quite being true single-step.

* JTAG: simple autoprobingDavid Brownell2009-10-261-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds basic autoprobing support for the JTAG scan chains which cooperate. To use, you can invoke OpenOCD with just: - interface spec: "-f interface/...cfg" - possibly with "-c 'reset_config ...'" for SRST/TRST - possibly with "-c 'jtag_khz ...'" for the JTAG clock Then set up config files matching the reported TAPs. It doesn't declare targets ... just TAPs. So facilities above the JTAG and SVF/XSVF levels won't be available without a real config; this is almost purely a way to generate diagnostics. Autoprobe was successful with most boards I tested, except ones incorporating C55x DSPs (which don't cooperate with this scheme for IR length autodetection). Here's what one multi-TAP chip reported, with the "Warn:" prefixes removed: clock speed 500 kHz There are no enabled taps. AUTO PROBING MIGHT NOT WORK!! AUTO auto0.tap - use "jtag newtap auto0 tap -expected-id 0x2b900f0f ..." AUTO auto1.tap - use "jtag newtap auto1 tap -expected-id 0x07926001 ..." AUTO auto2.tap - use "jtag newtap auto2 tap -expected-id 0x0b73b02f ..." AUTO auto0.tap - use "... -irlen 4" AUTO auto1.tap - use "... -irlen 4" AUTO auto2.tap - use "... -irlen 6" no gdb ports allocated as no target has been specified The patch tweaks IR setup a bit, so we can represent TAPs with undeclared IR length.

* ARM: rename "arm9tdmi vector_catch" to "arm9 ..."David Brownell2009-10-251-3/+2
| | | | | | And update doc accordingly. That EmbeddedICE register was introduced for ARM9TDMI and then carried forward into most new chips that use EmbeddedICE.

* SVF: clean up, mostly for TAP state name handlingDavid Brownell2009-10-231-1/+0
| | | | | | | | | | | | | | | | | | | | | - Use the name mappings all the other code uses: + name-to-state ... needed to add one special case + state-to-name - Improve various diagnostics: + don't complain about a "valid" state when the issue is actually that it must be "stable" + say which command was affected - Misc: + make more private data and code be static + use public DIM() not private dimof() + shorten the affected lines Re the mappings, this means we're more generous in inputs we accept, since case won't matter. Also our output diagnostics will be a smidgeon more informative, saying "RUN/IDLE" not just "IDLE" (emphasizing that there can be side effects).

* simplify XScale debug handler installationDavid Brownell2009-10-121-3/+0
| | | | | | | | | | | | | | | | | | | Load the XScale debug handler from the read-only data section instead of from a separate file that can get lost or garbaged. This eliminates installation and versioning issues, and also speeds up reset handling a bit. Plus some minor bits of cleanup related to loading that handler: comments about just what this handler does, and check fault codes while writing it into the mini-icache. The only behavioral changes should be cleaner failure modes after errors during handler loading, and being a bit faster. NOTE: presumes GNU assembly syntax, with ".incbin"; and ELF, because of the syntax of the ".size" directive. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
