# 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
