After doing:
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- bcm2835_defconfig
I had to enable:
CONFIG_6LOWPAN=y
CONFIG_6LOWPAN_NHC=y
CONFIG_6LOWPAN_NHC_DEST=y
CONFIG_6LOWPAN_NHC_FRAGMENT=y
CONFIG_6LOWPAN_NHC_HOP=y
CONFIG_6LOWPAN_NHC_IPV6=y
CONFIG_6LOWPAN_NHC_MOBILITY=y
CONFIG_6LOWPAN_NHC_ROUTING=y
CONFIG_6LOWPAN_NHC_UDP=y
CONFIG_IEEE802154=y
CONFIG_IEEE802154_SOCKET=y
CONFIG_IEEE802154_6LOWPAN=y
CONFIG_MAC802154=y
CONFIG_IEEE802154_FAKELB=y
CONFIG_IEEE802154_AT86RF230=y
CONFIG_IEEE802154_MRF24J40=y
CONFIG_IEEE802154_CC2520=y
and then I had a kernel that saw my at86 device. (I'm sure that the CC2520
and MRF24J40 enable was gratuitous).
I haven't yet interoperated with contiki; just ran out of time.
