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.

FreeCalypso original work ========================= The present FreeCalypso firmware is a derived work based on TI's TCS211 and TCS3.2 firmwares. However, even though it is based on these two starting points from TI, our FreeCalypso fw is a software product in its own right, and is NOT merely a "hacked" copy of some TI firmware. The particular way in which we have combined and integrated pieces from TCS211 and from TCS3.2 to produce our TCS2/TCS3 hybrid, our meticulous source reconstruction of TCS211 L1 that originally came in binary object form, our completely new and original firmware configuration and build system, all of our new code that supports new board- level hardware targets that use TI chips but aren't TI's historical development boards, and all other significant new developments made in FreeCalypso constitute our own original work. All original work in FreeCalypso that is not directly traceable to some historical TI code component has been written by Mother Mychaela Nadezhda Falconia, and I refuse to claim copyright on this software work. I hereby immediately place this work in the public domain; it may be used, copied, distorted or destroyed in any manner whatsoever without further attribution or notice to the creator. Code pieces from TI =================== In the case of those code components which originate from TI, we did not get them *from* TI per se, instead we have found them freely on the Internet. I, Mother Mychaela, have made multiple attempts to reach out to TI, informing them about the existence of our FreeCalypso family of projects and what I am doing with their old abandoned software IP. I was not able to get any positive response from them in the form of support or help with obtaining those pieces of historical code and documentation which are still missing, but they have not taken any adverse action against us either; specifically, they never said explicitly that they object to what I am doing (producing and freely distributing my own Derived Works based on their abandonware IP), and they never asked me to stop doing so. Based on the fact that TI have chosen to not take any action against our family of projects despite being fully informed and having been given multiple opportunities to do so over the course of many years, we hereby make the reasonable conclusion that TI do not object to us using their fully abandoned and discontinued IP as if it were Free Software, and I, Mother Mychaela, shall continue doing the same for as long as I am alive and physically able.
