David Brownell <david-b@pacbell.net>: 

DM6446 config updates:

 - List two more TAPs, as disabled, mostly for doc purposes
 - Included basic ICEpick support, still disabled by default
 - Shorten line lengths
 - Use $_TARGETNAME to configure the ETM and ETB
 - This ARM core don't support endianness overriding

For now, boards that can't jumper EMU0/EMU1 will need to tweak
a variable's setting.

# For now, expect EMU0/EMU1 jumpered LOW (not TI's default) so ARM and ETB

# Also note: when running without RTCK before the PLLs are set up, you
# may need to slow the JTAG clock down quite a lot (under 2 MHz).
