- fix warnings during configure cause by ecosboard. default to no, if host cpu isn't arm.
- fix generic bitbang code to allow scans to end in Shift-[ID]R
- several CFI fixes (thanks to Michael Schwingen):
- buffer overflow when converting target code in cfi_intel_write_block -
cfi_fix_code_endian needs the number of words, not bytes, as size
argument.
- Spansion flash write was completely broken on big-endian targets - I
borrowed mechanisms from the intel driver, and moved some common code
into the cfi_command_val helper function. There is still more common code
that might be cleaned up.
- the buffer size check in cfi_write was broken for spansion flashes, where
cfi_write_words is not implemented. cfi_write_words is no only called if
the flash does have a buffer size >1.
- "flash info" printed CFI status information for non-CFI flashes, which is
confusing. It now only prints those when a real CFI flash is detected.

- adds two speeds to jtag_speed. reset and post reset speed. Default
is post reset = reset speed.
- removed infinite loop's and exit()'s upon poor arm7/9 communication
- cleaned up error messages a bit. Push ERROR() up into fn's that
fail and can say something meaningful about what failed.

different events. Only TRST released has a DEBUG() statement

- fixed jtag_add_reset(). It no longer causes jtag_execute_queue() to
fail for two of it's return codes. A little bit weird, but compatible with
existing codebase.
- tightend up error handling. Since the jtag_xxx() is a queue that is either
executed as things are added(hw queue) or a software queue, then
errors can only be caught during jtag_execute_queue(). No error
code is therefore returned from the queuing fn's.

- hmm..... did I screw up? Was XScale and not gdb_server busted here?
My thinking was that OpenOCD has a canonical internal representation
of registers that match GDB's expectations

- the jtag chain is examined and validated after GDB & telnet servers
are up and running. The examination and validation is actually
"optional" from the point of view of GDB + telnet servers.
Multiple targets should work fine with this.
- jtag_speed is dropped(divisor is increased), if jtag examination and
validation fails.
- the chain is validated 10x to catch the worst jtag_speed offences
- added LOG_SILENT that can be used to shut up log. Feeble
ersatz for try+catch.
- GDB register packets are now always replied in order to make sure
that GDB connect works. If the target is not halted, then these
packets contain dummy values.

- Improves error handling upon GDB connect
- switch to synchronous halt during connect. This fixes the bug
where poll() was not invoked between halt() and servicing the
'g' register packet
- halt() no longer returns error code when target is already halted, just
logs a warning. Only the halt() implementation can say anything
meaningful about why a halt() failed, so error messages are pushed
up to halt()
- fixed soft_reset_halt infinite loop bug in arm7_9_common.c. The rest
of the implementations are still busted.
- by using USER() instead of command_print() the log gets the
source + line #. Nice.
- no longer invoke exit() if soft_reset_halt fails. A reset can often
fix the problem.
