+# Concerning the FFS, there is one fundamental difference between the gtamodem
+# and pirelli targets: whereas the content of Openmoko's modem FFS is directly
+# fit for reuse by our fw (resulting from the phylogenetic proximity of the two
+# firmwares), Pirelli's original FFS has the same format, but its content is so
+# different that trying to reuse it would be more trouble than it is worth.
+# (And Pirelli's FFS contains no IMEI or RF calibration data to boot!)
+#
+# Therefore, I (FC developer Michael Spacefalcon) have decided that when
+# targeting the Pirelli, it would be better for us to start from our own blank
+# FFS than to deal with the original.  This feature pirhack-ffs configures our
+# GSM fw to put its FFS in the last 7 256 KiB sectors of the 2nd flash chip
+# select: these sectors form an independent read/write bank, and are not used
+# for FFS by Pirelli's fw, eliminating the possibility of accidental FFS
+# cross-contamination between the two very different firmwares on the same hw.
