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.
