FFS dev.c: added Spansion PL032J to the "generic" table With the discovery of first GTM900 and then Tango, it now appears that Openmoko was not the only manuf after all who kept TI's TCS211 firmware largely intact (as opposed to changing it beyond all recognition like Compal, Chi-Mei and BenQ did), thus we are now getting new "alien" targets on which we reuse the original manuf's FFS with IMEI and RF calibration tables as if it were native. On these targets we use the original device table for FFS, even though we previously thought that it would never apply to any target other than dsample, leonardo and gtamodem. We have previously added Samsung K5L33xxCAM (a new kind of multi-ID device) to the generic table to support its use in Huawei GTM900-B modules; now we got news that some slightly older GTM900-B specimen used S71PL032J instead, so we are now adding PL032J as well.

# 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;
