1) NAND device memory is not directly accessible to CPU, its indirectly accessed via registers. So the 'reg' property for GPMC NAND nodes should be limited to address range of internal GPMC registers only. 2) Also, minimum granularity of address space under a GPMC chip-select is 16MB so 'range' property for GPMC NAND node should specify 16MB as its memory-size 3) On AM437x, address map of external memory accessible via GPMC starts from 0x0
