- Shrink messaging during resets, primarily by getting rid of
   "nothing happened" noise that hides *useful* information.

 - Improve: the "no IDCODE" message by identifying which tap only
   supports BYPASS; and the TAP event strings.

Related minor code updates:

 - Remove two needless tests when examining the chain:  we know
   we have a TAP, and that all TAPs have names.

 - Clean up two loops, turning "while"s into "for"s which better
   show what's actually being done.

for disabling TAPs.  We don't actually know how to make any
JRCs which do that yet; but when we do, this will matter.

and Tcl/external):

 - Reorder so *both* paths (TCK/TMS or TRST) can enable TAPs with
   ICEpick ... first C code flags TAPs that got disabled, then call
   any Tcl code that might want to re-enable them.

 - Always call the C/internal handlers when JTAG operations can be
   issued; previously that wasn't done when TRST was used. 

Plus some small cleanups (whitespace, strings, better messaging
during debug and on some errors) to reset-related code.

avoid a duplicate test.

Plus other cleanup in the same code: be "static", sane line lengths
for source and diagnostics, and fix misleading variable names.

Erase logic:
 - command invocation
    + treat "nand erase N" (no offset/length) as "erase whole chip N"
    + catch a few more bogus parameter cases, like length == 0 (sigh)
 - nand_erase() should be static
 - on error
    + say which block failed, and if it was a bad block
    + don't give up after the first error; try to erase the rest
 - on success, say which nand device was erased (name isn't unique)

Device list ("nand list"):
 - say how many blocks there are
 - split summary into two lines
 - give example in the docs

Doc tweaks:
 - Use @option{...} for DaVinci's supported hardware ECC options

For the record, I've observed that _sometimes_ erasing bad blocks causes
failure reports, and that manufacturer bad block markers aren't always
erasable (even when erasing their blocks doesn't trigger an error report).

 - update docs to clarify that the "arm9tdmi" command prefix
   is a misnomer.
 - bugfix some messages that wrongly assume only ARM9TDMI
   based processors use this code.

JTAG clocking by gating the core clock, and workarounds.
Most details are with the "halt" command, which is one
of the first places this issue will be noticed.

Update the board config for the DaVinci DM355 EVM so the reset-init
event handler does the rest of the work it should do:

 - minor PLL setup bugfixes
 - initialize the DDR2 controller
 - probe both NAND banks
 - initialize UART0
 - enable the icache

Cleanup some the downloaded ARM target algorithm code:

 - Provide more complete disassembly of the DCC bulk write code

 - Make code blocks "static const", in case GCC doesn't

 - Fix some tabbing/layout issues

 - Make some arm7_9_common.h flags be "bool" not "int"; and compact
   the layout a bit (group most bools together)
