−# 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
