Identical to the existing 2412/2443 support except for the base address
and NFCONF value (bit 2 is reserved and should be written as 1 ref UM).
Tested on a s3c6410 board, but controller is identical in 6400/6410
except for 8bit MLC ECC support in 6410 which isn't supported by the
driver.

Capture various bits of useful information that have come up on the
list but haven't yet gotten into the documentation:
- Watchdog timers firing during JTAG debug need attention;
- Some chips have special registers to help JTAG debug;
- Cortex-M3 stepping example with IRQs and maskisr;
- Clarifications re adaptive clocking: not all ARMs do it, and
explain it a bit better.

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".

The "parport_port" commands generally don't *require* a port_number;
they're of the "apply any parameter, then print result" variety. Update
the User's Guide accordingly.
Some of those commands are intended to be write-once: parport_port,
and parport_cable. Say so.
Use proper EBNF for the parport_write_on_exit parameter.
Parport address 0xc8b8 is evidently mutant. Say so in the "parport.cfg"
file, to avoid breaking anyone with that mutant config. But update the
User's Guide to include a sane example for the LP2 port.
Finally document the "presto_serial" command.

Most commands are usable only at runtime; so don't bother saying
that, it's noise. Moreover, tokens like EXEC are cryptic. Be
more clear: highlight only the commands which may (also) be used
during the config stage, thus matching the docs more closely.
There are
- Configuration commands (per documentation)
- And also some commands that valid at *any* time.
Update the docs to note that "help" now shows this mode info.
This also highlighted a few mistakes in command configuration,
mostly commands listed as "valid at any time" which shouldn't
have been. This just fixes ones I noted when sanity testing.

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.

Resolve a regression when using newish automagic "write_image"
modes, by always padding to the end of affected sectors.
Also document some issues associated with those automagic options,
in the User's Guide and also some related code comments.
We might need similar padding at the *beginning* of some sectors,
but this is a minimalist fix for the problems which have currently
been reported (plus doc updates).
