Fix a bug preventing ICEpick "enable that TAP" code from working:
the "runtest" command wrongly finished with a JTAG reset, discarding
the work the TAP enable handler just finished!  Instead, JTAG should
stay in RUN/IDLE state.

zwelch a0c10dd29b David Brownell <david-b@pacbell.net>:
Extend the internal JTAG event handlers to cover enable/disable,
and use those events to make sure that targets get "examined" if
they were disabled when the scan chain was first set up:

 - Remove "enum jtag_tap_event", merge with "enum jtag_event",
   so C code can now listen for TAP enable/disable events.

 - Report those events so they can trigger callbacks.

 - During startup, make target_examine() register a handler to
   catch ENABLE events for any then-disabled targets.

This fixes bugs like "can't halt target after enabling its TAP".

One class of unresolved bugs:  if the target has an ETM hooked
up to an ETB, nothing activates the ETB.  But starting up the
ETM without access to the ETB registers fails...

zwelch 491083a248 David Brownell <david-b@pacbell.net>:
Tighten error handling on TAP enable/disable paths a bit:

 - Don't enable/disable unless it's necessary.  Those event
   handlers could have nasty side effects...

 - Don't *succeed* enables/disables if there was no code which
   could have implemented that action.  This prevents bugs like
   wrongly acting as if the scan chain changed.

 - Minor whitespace cleanup in enable/disable command code.

The big problem is still the lack of code to verify scan chains
were actually updated as requested; this adds a comment on that.
I suspect the best we can do near term will be to verify IDCODE.

Distributing FTDI's "ftd2xx" library with OpenOCD violates the
OpenOCD license (GNU GPLv2 with no exceptions).

Make that clear where that build option is presented, and don't
describe the FTDI libraries as an option for any packager.  (It's
fine for personal use, of course.)

Plus some related clarifications:  libftdi version 0.16 for the
new FT2232H chips (for RTCK and high speed USB); the Amontec
drivers are just ftd2xx variants.

zwelch 14f88acaf6 David Brownell <david-b@pacbell.net>:
Fix some polling issues:

 - Don't background-poll disabled TAPs ... this was just a bug
   waiting to happen.  (And then it happened!)

 - Don't fail command line polls of disabled taps; that's not any
   kind of error, it's just that you can't do much.  But do show
   that tap-disabled status.

 - Spell "continuous" correctly in the variable name.  ;)

Not resolved by this patch:  the need for an interlock whereby
other code (like the JTAG layer) can block all other access to
the JTAG layer, e.g. while enabling or disabling TAPs.  And
that interlock needs to be timer-safe...

Doc update:  say "jtag newtap ... -disable" records the
state after exiting the RESET state, matching the only
implementation we're working with so far (TI ICEpick-C).

Matching code updates.  Now we can be sure that the
"enabled" flag value is correct after JTAG resets.

zwelch 03803a9d79 David Brownell <david-b@pacbell.net>:
Fix a memory leak in jtag_tap_free():  unregister the event
callback too.

Also fix the associated conceptual bug in unregistering JTAG
event callbacks:  since the same callback procedure is used
many times with different callback data (a TAP handle), that
data must be considered when unregistering any callback.

This could fix some crashes after TAP registration errors,
by making sure the reset event handler doesn't scribble over
memory that's now used by something else.

Add another board ... OMAP2420 "H4" board.  This won't be very widely
used with OpenOCD, but with mainline support in both U-Boot and Linux
it at least makes for a more complete set (and another testcase).

This is incomplete support in several respects.  The ARM11 support is
not very deep yet; most registers aren't available, and the ETM can't
be hooked up.  Plus, there's no script for OMAP-specific stuff like
setting up the SDRAM controller.  Eventually the same NAND controller
driver should work with OMAP2 and OMAP3.

Currently the "debug_level 3" command tracing ignores commands
that could return values to TCL scripts (by plugging in to a
slightly lower level of the interpreter stack).

Fix that by abstracting the tracing command and starting to
make some of those previously-untraced commands use this new
mechanism.

Partial fix to the "long IR length" problems.

 - Current code could handle up to 32 bit IR lengths with
   full functionality, if it didn't just reject may of them
   out of hand.  So only reject clear errors, where the IR
   mask (or capture instruction) needs more than IrLen bits.

 - Longer IR lengths can only be handled in BYPASS mode
   for now.  Example:  TI's DSPs use 38-bit IR lengths.
   So we can't issue their IDCODE instructions...

A more complete fix would be able to issue longer instructions;
or minimally, would fail cleanly for the non-BYPASS case.

Note that this *could* make some currently broken scripts fail,
since the previous code accepted garbage values so long as
they didn't use more than 16 bits.

zwelch c6e80f63a3 David Claffey <dnclaffey@gmail.com>:
This patch helps fix MIPS big endian (elf32-tradbigmips) targets.
If "-endian big" is not set in target create, the endianess defaults to
little.  mw and md commands will still work, but binary file loads will
have the incorrect word order loaded into memory.

The EJTAG processor access data register (PrAcc) is little endian
regardless of the CPU endianness; it is always loaded LSB first. This
is confirmed by the fact that mips_ejtag_drscan_32() uses buf_set_u32()
to load the scan field; buf_set_u32() is a little-endian formatter. For
big endian targets, data buffers have to be modified so the LSB of each
u32 or u16 is at the lower (first) memory location.  If the drscan
out_value word order is set using buf_set_u32() then it makes sense to
also fixup the in_value with buf_get_u32(); a symmetry argument. This
has no affect on little endian hosts.
