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.

This makes it so that the usage/help command properly uses the whole command,
including subcommand, in the search for help information.  This previously

I wanted to make it so I can be ignorant of a commands invocation string, so
I tried to use CMD_CURRENT (aka cmd->current) which is supposed to house a
pointer to the current command.  It turns out that this wasn't being set.

This patch adds the current command structure to the command invocation
structure before sending it along to the command handler.

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.

This config is only lightly tested, and doesn't work well yet;
but it's a start.

 * Notably missing is PLL configuration, since each DaVinci
   does that just a bit differently; and thus DDR2 setup.

 * The SRST workaround needed for the goof in the CPLD's VHDL
   depends on at least the not-yet-merged patch letting ARM9
   (and ARM7) chips perform resets that don't use SRST.

So this isn't yet suitable for debugging U-Boot.

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).

Modern versions of GDB can understand VFP3 and iwMMXt hardware.

Advise leaving background polling enabled; fix broken URL;
add simple program startup example.

Fix syntax error:  default to "wrote N bytes"; writing a
single byte is an unusual case, not the normal one.

Switch to calloc() to simplify review and initialization.

It's less accepting of signed char ... insisting that e.g. tolower()
not receive one as a parameter.

It's probably good to phase out such usage, given the number of bugs
that lurk in the vicinity (assumptions that char is unsigned), so fix
these even though such usage is actually legal.
