What are your bootargs?
I suggest putting the flash device into the dts (instead of using
physmap), and specifying the partitions on the command-line using
mtdparts. Putting the partitions in the dts is an option as well, but
less flexible if users may want to change the partition layout -- though
that may be less of a concern here than with reference boards.
