niq32.c DTR handling restored for targets that have it
TI's original TCS211 fw treated GPIO 3 as the DTR input (wired so on C-Sample
and D-Sample boards, also compatible with Leonardo and FCDEV3B which have a
fixed pull-down resistor on this GPIO line), and the code in niq32.c called
UAF_DTRInterruptHandler() (implemented in uartfax.c) from the
IQ_KeypadGPIOHandler() function. But on Openmoko's GTA02 with their official
fw this GPIO is a floating input, all of the DTR handling code in uartfax.c
including the interrupt logic is still there, but the hobbled TCS211-20070608
semi-src delivery which OM got from TI contained a change in niq32.c (which
had been kept in FC until now) that removed the call to
UAF_DTRInterruptHandler() as part of those not-quite-understood "CC test"
hacks.
The present change fixes this bug at a long last: if we are building fw for a
target that has TI's "classic" DTR & DCD GPIO arrangement (dsample, fcmodem and
gtm900), we bring back all of TI's original code in both uartfax.c and niq32.c,
whereas if we are building fw for a target that does not use this classic GPIO
arrangement, the code in niq32.c goes back to what we got from OM and all
DTR & DCD code in uartfax.c is conditioned out. This change also removes the
very last remaining bit of "CC test" bogosity from our FreeCalypso code base.
