It seems the nand chips are never described and on 1 board even has partitions. I think you should fix the dts to move 'partition@N' nodes under 'partitions' which is preferred and needed if you ever describe nand chips. And then fix '#size-cells' to be 0. Rob

Most of Freescale/NXP GPMI device trees use size-cells==1 (even when actually not needed except few boards).
