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.

# TI's original version of the pf_TaskEntry() function in the guts of GPF
# does this number once all GPF tasks have entered their main loop:
#
#    TraceMask[0] = 0;
#
# The effect of this line is that "system" trace output gets disabled;
# in particular, "system primitive" requests like querying for existing
# TRACECLASS of various entities or for the GPF version elicit no response
# whatsoever until one sends a TRACECLASS setting sysprim which restores
# the TC_SYSTEM bit in TraceMask[0].
#
# In FreeCalypso we consider this clearing of TraceMask[0] to be either
# a bug or a misfeature, and we would like to change it.  In the case of
# the GPF code in question, we do have a copy of frame.c source (the module
# where the offending pf_TaskEntry() function is implemented) which we believe
# is the same code as what's in the TCS211 version of GPF, but TCS211 is not
# set up to recompile any part of GPF from source, and there are other modules
# in the same frame_na7_db_ir.lib for which we don't have the original source
# (os_*), hence it is easier to do a binary lib patch.
#
# The present patch is a binary form of:
#
# -TraceMask[0] = 0;
# +TraceMask[0] = TC_SYSTEM;
