FFS dev.c, Leonardo target: Fujitsu MB84VF5F5F4J2 #if 0'ed out The FFS code we got from TI/Openmoko had a stanza for "Fujitsu MB84VF5F5F4J2 stacked device", using a fake device ID code that would need to be patched manually into cfgffs.c (suppressing and overriding autodetection) and using an FFS base address in the nCS2 bank, indicating that this FFS config was probably meant for the MCP version of Leonardo which allows for 16 MiB flash with a second bank on nCS2. We previously had this FFS config stanza conditionalized under CONFIG_TARGET_LEONARDO because the base address contained therein is invalid for other targets, but now that we actually have a Leonardo build target in FC Magnetite, I realize that the better approach is to #if 0 out this stanza altogether: it is already non-functional because it uses a fake device ID code, thus it is does not add support for more Leonardo board variants, instead it is just noise.

# 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;
