pcmdata.c: default +CGMI to "FreeCalypso" and +CGMM to model
The present change has no effect whatsoever on Falconia-made and Openmoko-made
devices on which /pcm/CGMI and /pcm/CGMM files have been programmed in FFS
with sensible ID strings by the respective factories, but what should AT+CGMI
and AT+CGMM queries return when the device is a Huawei GTM900 or Tango modem
that has been converted to FreeCalypso with a firmware change? Before the
present change they would return compiled-in defaults of "<manufacturer>" and
"<model>", respectively; with the present change the firmware will self-identify
as "FreeCalypso GTM900-FC" or "FreeCalypso Tango" on the two respective targets.
This firmware identification will become important if someone incorporates an
FC-converted GTM900 or Tango modem into a ZeroPhone-style smartphone where some
high-level software like ofono will be talking to the modem and will need to
properly identify this modem as FreeCalypso, as opposed to some other AT command
modem flavor with different quirks.
In technical terms, the compiled-in default for the AT+CGMI query (which will
always be overridden by the /pcm/CGMI file in FFS if one is present) is now
"FreeCalypso" in all configs on all targets; the compiled-in default for the
AT+CGMM query (likewise always overridden by /pcm/CGMM if present) is
"GTM900-FC" if CONFIG_TARGET_GTM900 or "Tango" if CONFIG_TARGET_TANGO or the
original default of "<model>" otherwise.

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.
