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.
