after clocking out a tms sequence, then the TAP will be
in some state. This state is now handed to the drivers.
TAP_INVALID is a possible state after a TMS sequence if
switching to SWD.

The Redbee USB is a small form-factor usb stick from Redwire, LLC
(www.redwirellc.com/store), built around a Freescale MC13224V
ARM7TDMI + 802.15.4 radio (plus antenna).
It includes an FT2232H for debugging, with Channel B connected to the
mc13224v's JTAG interface (unusual) and Channel A connected to UART1.

The Redbee Econotag is an open hardware development kit from
Redwire, LLC (www.redwirellc.com/store), for the Freescale
MC13224V ARM7TDMI + 802.15.4 radio.
It includes both an MC13224V and an FT2232H (for JTAG and UART
support). It has flexible power supply options.
Additional features are:
- inverted-F pcb antenna
- 36 GPIO brought out to 0.1" pin header
(includes all peripheral pins)
- Reset button
- Two push buttons (on kbi1-5 and kbi0-4)
- USB-A connector, powered from USB
- up to 16V external input
- pads for optional buck inductor
- pads for optional 32.768kHz crystal
- 2x LEDS on TX_ON and RX_ON

For support of SWD we need to be able to clock out special bit
sequences over TMS or SWDIO. Create this as a generic operation,
not yet called by anything, which is split as usual into:
- upper level abstraction ... here, jtag_add_tms_seq();
- midlayer implementation logic hooking that to the lowlevel code;
- lowlevel minidriver operation ... here, interface_add_tms_seq();
- message type for request queue, here JTAG_TMS.
This is done slightly differently than other operations: there's a flag
saying whether the interface driver supports this request. (In fact a
flag *word* so upper layers can learn about other capabilities too ...
for example, supporting SWD operations.)
That approach (flag) lets this method *eventually* be used to eliminate
pathmove() and statemove() support from most adapter drivers, by moving
all that logic into the mid-layer and increasing uniformity between the
various drivers. (Which will in turn reduce subtle bugginess.)

FT2232-family chips have two or more MPSSE modules. FTDI documentation
calls these channels. JTAG adapter drivers thus need to be able to choose
which channel to use. (For example, one channel may connect to a board's
microcontroller, while another connects to a CPLD.)
Since each channel has its own USB interface, libftdi (somewhat confusingly)
identifies channels using INTERFACE_* symbols. Most boards use INTERFACE_A
for JTAG, which is the default in OpenOCD. But some wire up a different one.
Note that there are two facets of what makes a wiring "layout":
- The mapping between debug signals map and channel signals ... embedded
in C functions.
- Label used in Tcl configuration scripts ... part of the "layout" structure.
By letting the channel be part of the layout struct, we permit sharing the C
functions between Tcl-visible layouts, when those signal mappings are reused.

This allows minidrivers to e.g. hardware accelerate memory
writes.
Same trick as is used for arm7/9 dcc writes.
Added error propagation for memory transfer failures in
code rearrangement.
Also the JTAG end state is not updated until after
the memory write run is complete.

The very first command after init command should be "read target voltage".
This is a tweak for the Old Versaloon firmware. Without this, in most
most cases, it works. Under Ubuntu9.04, there is a chance that the USB
will fail. The problem disappears if I read target voltage first.
For the lastest Versaloon firmware, it's OK.

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.
