* simplify XScale debug handler installationDavid Brownell2009-10-126-45/+59
| | | | | | | | | | | | | | | | | | | 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>
* more xscale cleanup (mostly removing JTAG hooks)David Brownell2009-10-122-88/+65
| | | | | | | | | | | | | | | | 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>

| * xscale bugfix to handler loadingDavid Brownell2009-10-111-2/+2
| | | | | | | | | | | | | | | | | | 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.

| * xscale minor cleanupDavid Brownell2009-10-111-43/+31

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>

| * make PXA255 targets enumerate sort-of-OKDavid Brownell2009-10-082-3/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * add overridable Tcl "init_reset"David Brownell2009-10-082-8/+23
| | | | | | | | | | | | | | | | | | | | | | 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.

* initial builds of OSK5912 boards need srst_pulls_trstDavid Brownell2009-10-081-0/+4
| | | | | | | | | | | | 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.

* prevent abort via polling during jtag_resetDavid Brownell2009-10-083-9/+51
| | | | | | | | | | | | | 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.

* Stop ignoring most scan chain validation errorsDavid Brownell2009-10-082-15/+50
| | | | | | | | | | | | | | | | 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>
