2009-10-12arm11 burst writes are now only enabled for writes larger than 1 word. ↵Øyvind Harboe

2009-10-12simplify XScale debug handler installationDavid Brownell
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>
2009-10-12more xscale cleanup (mostly removing JTAG hooks)David Brownell
Streamline/shrink some needless JTAG stuff: - Use #defines for the JTAG instructions; they can't ever change - Remove an unused (!) shadow of tap->ir_length - Stop using a copy of target->tap - Don't bother saving the variant after sanity checking ir_length Also, make target_create() work as on other targets: build the register cache later, making init_target() no longer be a NOP. Handle malloc failure; remove a comment that was obsoleted by the not-so-new target syntax. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

2009-10-11xscale_load_ic cleanupDavid Brownell
Remove unused and deprecated (in the arch spec) mode for loading code into the *main* icache (vs the "mini" icache). Disable some extremely noisy (and rarely useful) low-level debug messages Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-11xscale.c cleanupDavid Brownell
Declare almost everything as static. Move stuff to remove most forward references. Remove most forward declarations. Warn if the unimplemented register functions get called. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-11xscale bugfix to handler loadingDavid Brownell
Just fill out the rest of the cache line with NOPs; don't change the record of how much data we consumed. Otherwise the count of how much data is left can roll over from positive to negative ("VERY positive") and skip the loop termination of zero. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-11xscale minor cleanupDavid Brownell
Add a header comment referencing useful XScale specs. Make most data static, and the tables readonly. Scrub extra blank lines. Return fault codes from one routine. Remove a needless NOP methood. (BUGFIX) When we update R0, mark R0 as dirty/valid ... not R15/PC! Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

2009-10-09add documentation about reset customizationDavid Brownell
We added two overridable procedures; document them, and the two jtag arp_* operations they necessarily expose. Update the comment about the jtag_init_reset() routine; it's been obsolete for as long as it's had SRST support. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

2009-10-08make PXA255 targets enumerate sort-of-OKDavid Brownell
Startup now mostly works, except that the initial target state is "unknown" ... previously, it refused to even start. Getting that far required fixing the ircapture value (which can never have been correct!) and the default JTAG clock rate, then providing custom reset script. The "reset" command is still iffy. DCSR updates, and loading the debug handler, report numerous DR/IR capture failures. But once that's done, "poll" reports that the CPU is halted (which it shouldn't be, this was "reset run"!), due to the rather curious reason "target-not-halted". Summary: you still can't debug these parts, but it's closer. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-08add overridable Tcl "init_reset"David Brownell
This abstracts the "jtag arp_init-reset" call into a method called from OpenOCD startup and reset processing. Platforms which have different requirements for how such hard resets must be performed can now override "init_reset" instead of needing to rebuild custom hacked versions of the server.

2009-10-08initial builds of OSK5912 boards need srst_pulls_trstDavid Brownell
This is clearly noted in the hardware spec (section 5.2.3); it works around a chip erratum: "If the MPU_RESET signal is used, it may cause the EMIFS bus to lock." I seem to have a board with such an initial build. The chip is labeled XOMAP. Presumably, parts without that "X" prefix (eXperimental) resolve this.

2009-10-08prevent abort via polling during jtag_resetDavid Brownell
Observed: openocd: core.c:318: jtag_checks: Assertion `jtag_trst == 0' failed. The issue was that nothing disabled background polling during calls from the TCL shell to "jtag_reset 1 1". Fix by moving the existing poll-disable mechanism to the JTAG layer where it belongs, and then augmenting it to always pay attention to TRST and SRST. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-10-08Stop ignoring most scan chain validation errorsDavid Brownell
Among other things this causes startup errors to kick in the fallback "reset harder" logic during server startup. Comments are also updated a bit, explaining what the various error paths signify (in at least my observation). There's one class of validation error that we can still plausibly ignore: when wrong IDCODE values are observed. This change seems to have helped make an OMAP5912 behave much more reliably. There's still some post-reset flakiness, but it's unrelated to scan verification. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

2009-10-07Force sane SRST and TRST initializationdbrownell
At least some FT2232 based adapters don't necessarily come up in the expected state, with SRST and TRST disabled. Since other adapters could suffer the same problem, let's avoid needing to patch every driver and just force *all* adapters to initialize those values properly at server startup. git-svn-id: svn://svn.berlios.de/openocd/trunk@2824 b42882b7-edfa-0310-969c-e2dbd0fdcd60
2009-10-07Better fix for TAPs violating the JTAG spec for IR-Capture.dbrownell
