+# feature mokoffs is applicable only when building gsm-fw for the Openmoko
+# GTA0x GSM modem.  This feature directs our fw to use the original FFS
+# which contains the factory IMEI + RF calibration data and which the
+# original mokoN firmware treats as writable.
+#
+# There are 3 different ways in which we can use MokoFFS:
+#
+# feature mokoffs rw	-- treat MokoFFS as R/W like the original fw does
+# feature mokoffs ro	-- use MokoFFS in flash, but disable flash write ops
+# feature mokoffs copy	-- copy MokoFFS into RAM on boot, then R/W in RAM only
