David Brownell 93f2afa45f initial "transport" framework
This adds the guts of a transport framework with initialization,
which should work with current JTAG-only configurations (tested
with FT2232).

Each debug adapter can declare the transports it supports, and
exactly one transport is initialized.  (with its commands) in
any given OpenOCD session.

  * Define a new "struct transport with init hooks and a few
 "transport"  subcommands to support it:

     "list" ... list the transports configured (just "jtag" for now)
     "select" ... makes the debug session use that transport
     "init" ... initializes the selected transport (internal)

  * "interface_transports" ... declares transports the current interface
    can support.  (Some will do this from C code instead, when there are
    no hardware versioning (or other) issues to prevent it.

Plus some FT2232 tweaks, including a few to streamline upcoming
support for an SWD transport (initially for Luminary adapters).

Eventually src/jtag should probably become src/transport, moving
jtag-specific stuff  to transport/jtag.

Clean up the jtag/tcl.c file, which was one of the biggest and
messiest ones in that directory.  Do it by splitting out all the
generic adapter commands to a separate "adapter.c" file (leaving
the "tcl.c" file holding only JTAG utilities).

Also rename the little-used "jtag interface" to "adapter_name", which
should have been at least re-categorized earlier (it's not jtag-only).

David Brownell 53b3d4dd53 LPC1768 updates, IAR board support
Fix some issues with the generic LPC1768 config file:

 - Handle the post-reset clock config:  4 MHz internal RC, no PLL.
   This affects flash and JTAG clocking.

 - Remove JTAG adapter config; they don't all support trst_and_srst

 - Remove the rest of the bogus "reset-init" event handler.

 - Allow explicit CCLK configuration, instead of assuming 12 MHz;
   some boards will use 100 Mhz (or the post-reset 4 MHz).

 - Simplify: rely on defaults for endianness and IR-Capture value

 - Update some comments too

Build on those fixes to make a trivial config for the IAR LPC1768
kickstart board (by Olimex) start working.

Also, add doxygen to the lpc2000 flash driver, primarily to note a
configuration problem with driver: it wrongly assumes the core clock
rate never changes.  Configs that are safe for updating flash after
"reset halt" will thus often be unsafe later ... e.g. for LPC1768,
after switching to use PLL0 at 100 MHz.

David Brownell e70d42a727 new "stellaris recover" command
Stellaris chips have a procedure for restoring the chip to
what's effectively the "as-manufactured" state, with all the
non-volatile memory erased.  That includes all flash memory,
plus things like the flash protection bits and various control
words which can for example disable debugger access.  clearly,
this can be useful during development.

Luminary/TI provides an MS-Windows utility to perform this
procedure along with its Stellaris developer kits.  Now OpenOCD
users will no longer need to use that MS-Windows utility.

David Brownell 73566405b6 NOR: add optional "flash erase_address" sector padding
Add a NOR flash mechanism where erase_address ranges can be padded
out to sector boundaries, triggering a diagnostic:

  > flash erase_address 0x0001f980 16
  address range 0x0001f980 .. 0x0001f98f is not sector-aligned
  Command handler execution failed
  in procedure 'flash' called at file "command.c", line 647
  called at file "command.c", line 361
  >

  > flash erase_address pad 0x0001f980 16
  Adding extra erase range, 0x0001f800 to 0x0001f97f
  Adding extra erase range, 0x0001f990 to 0x0001fbff
  erased address 0x0001f980 (length 16) in 0.095975s (0.163 kb/s)
  >

This addresses what would otherwise be something of a functional
regression.  An earlier version of the interface had a dangerous
problem:  it would silently erase data outside the range it was
told to erase.  Fixing that bug turned up some folk who relied on
that unsafe behavior.  (The classic problem with interface bugs!)
Now they can get that behavior again.  If they really need it,
just specify "pad".

David Brownell d91941d5a0 Cortex-M3: improved core exception handling
This updates three aspects of debugger/exception interactions:

 - Save the user's "vector_catch" setting, and restore it after reset.
   Previously, it was obliterated (rather annoyingly) each time.

 - Don't catch BusFault and HardFault exceptions unless the user says
   to do so.  Target firmware may need to handle them.

 - Don't modify SHCSR to prevent escalating BusFault to HardFault.
   Target firmware may expect to handle it as a HardFault.

Those simplifications fix several bugs.  In one annoying case, OpenOCD
would cause the target to lock up on ome faults which triggered after
the debugger disconnected.

NOTE:  a known remaining issue is that OpenOCD can still leave DEMCR
set after an otherwise-clean OpenOCD shutdown.

David Brownell ec297e4bf1 Fix Luminary FT2232 layout docs/configs
Most of this patch updates documentation and comments for various
Luminary boards, supporting two bug fixes by helping to make sense
of the current mess:

 - Recent rev C lm3s811 eval boards didn't work.  They must use
   the ICDI layout, which sets up some signals that the older
   boards didn't need.  This is actually safe and appropriate
   for *all* recent boards ... so just make "luminary.cfg" use
   the ICDI layout.

 - "luminary-lm3s811.cfg", was previously unusable!  No VID/PID;
   and the wrong vendor string.  Make it work, but reserve it
   for older boards where the ICDI layout is wrong.

 - Default the LM3748 eval board to "luminary.cfg", like the
   other boards.  If someone uses an external JTAG adapter, all
   boards will use the same workaround (override that default).

The difference between the two FT2232 layouts is that eventually
the EVB layout will fail cleanly when asked to enable SWO trace,
but the ICDI layout will as cleanly be able to enable it.  Folk
using "luminary.cfg" with Rev B boards won't see anything going
wrong until SWO support is (someday) added.

David Brownell abe8b43755 ETM: add "etm trigger_debug" command
In conjunction with manual register setup, this lets the ETM trigger
cause entry to debug state.   It should make it easier to test and
bugfix the ETM code, by enabling non-trace usage and isolating bugs
specific to thef ETM support.  (One current issue being that trace
data collection using the ETB doesn't yet behave.)

For example, many ARM9 cores with an ETM should be able to implement
four more (simple) breakpoints and two more (simple) watchpoints than
the EmbeddedICE supports.  Or, they should be able to support complex
breakpoints, incorporating ETM sequencer, counters, and/or subroutine
entry/exit criteria int criteria used to trigger debug entry.

David Brownell 3f18900b19 NOR FLASH: only erase/unlock whole sectors
Much to my surprise, I observed a "flash erase_address ..."
command erasing data which I said should not be erased.

The issue turns out to be generic NOR flash code which was
silently, and rather dangerously, morphing partial-sector
references into unrequested whole-sector ones.

This patch removes that low-level morphing.  If desired, it
can and should be done in higher level code.  (We might need
to fix some stuff in the GDB server code.)

Nicolas Pitre ed59dfc80a basic ARM semihosting support
Semihosting enables code running on an ARM target to use the
I/O facilities on the host computer. The target application must
be linked against a library that forwards operation requests by
using the SVC instruction that is trapped at the Supervisor Call
vector by the debugger.  The "hosted" library version provided
with CodeSourcery's Sourcery G++ Lite for ARM EABI is one example.

This is currently available for ARM9 processors, but any ARM
variant should be able to support this with little additional work.

Tested using binaries compiled with Sourcery G++ Lite 2009q1-161
and ARM RVCT 3.0.

David Brownell 60e24aa597 make PXA255 targets enumerate sort-of-OK
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.
