fc-shell TCH DL handler: add support for CSD modes TCH DL capture mechanism in FC Tourmaline firmware has been extended to support CSD modes in addition to speech - add the necessary support on the host tools side. It needs to be noted that this mechanism in its present state does NOT provide the debug utility value that was sought: as we learned only after the code was implemented, TI's DSP has a misfeature in that the buffer we are reading (a_dd_0[]) is zeroed out when the IDS block is enabled, i.e., we are reading all zeros and not the real DL bits we were after. But since the code has already been written, we are keeping it - perhaps we can do some tests with IDS disabled.

# The present hw parameter file is a minimal config that is appropriate to use
# if the target is known to have a Calypso C05 chip and a Iota ABB chip, but
# nothing else is known.  This minimal config is not usable for flash
# manipulation or for fc-xram, but it may be useful for fc-iram or low-level
# (non-flash) fc-loadtool operations.  This config is also a good choice for
# fc-buzplay and fc-dspromdump.

# The following parameters go into the <p command sent to the boot ROM
pll-config 3/1		# ARM @ 39 MHz, PLL&DSP @ 78 MHz if 26 MHz in
rhea-cntl 0x00		# good for all Calypso platforms

# Perform a Iota poweroff when we are done
