JTAG: simple autoprobing
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.

xscale: always reload handler after reset
Remove needless debug handler state.
- "handler_installed" became wrong as soon as the second TRST+SRST
reset was issued ... so the handler was never reloaded after the
reset removed it from the mini-icache.
This fixes the bug where subsequent resets fail on PXA255 (if the
first one even worked, which is uncommon). Other XScale chips
would have problems too; PXA270 seems to have, IXP425 maybe not.
- "handler_running" was never tested; it's pointless.

XSVF: use svf_add_statemove()
XSVF improvements:
- Layer parts of XSVF directly over SVF, calling svf_add_statemove()
instead of expecting jtag_add_statemove() to conform to the SVF/XSVF
requirements (which it doesn't).
This should improve XSTATE handling a lot; it removes most users of
jtag_add_statemove(), and the comments about how it should really do
what svf_add_statemove() does.
- Update XSTATE logic to be a closer match to the XSVF spec. The main
open issue here is (still) that this implementation doesn't know how
to build and submit paths from single-state transitions ... but now
it will report that error case.
- Update the User's Guide to mention the two utility scripts for
working with XSVF, and to mention the five extension opcodes.
Handling of state transition paths is, overall, still a mess. I think
they should all be specified as paths not unlike SVF uses, and compiled
to the bitstrings later ... so that we can actually make sense of the
paths. (And see the extra clocks, detours through RUN, etc.)

xscale: stackframe corruption bugfix
Resolve a "FIX" comment; yes that was superfluous given that the
JTAG core does that check by default. It was also buggy since it
wrote to a stack frame that went away before the write happened!!
Other fixes: remove pointless malloc(); zero-init scan_field_t
values wherever they appear; whitespace scrub; spelling fix.

simplify XScale debug handler installation
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.

more xscale cleanup (mostly removing JTAG hooks)
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.
