compile-fc-batt: allow possible third field in source lines Battery tables maintained in the fc-battery-conf repository will now have a third field added, defining thresholds for the battery bars icon, and there will be a new utility to compile them into the new /etc/batterytab2 file read by the FC Tourmaline version of our FCHG driver. For backward compatibility with the original Magnetite version of FCHG, compile-fc-batt remains the tool for compiling the original /etc/batterytab file format, and it needs to ignore the newly added third field in battery table sources.

# This loadtool init script provides memory interface register setup
# for targets which fit the following criteria:
#
# Classic chip select arrangement: nCS0 for flash and nCS1 for XRAM
# 4 wait states are to be used (register setting 00A4)
# No ADD22 - both flash and XRAM are 4 MiB or less
