Thats exactly what I want to do. If you say not to use physmap with
NAND, how he is doing this? Through the device tree source?

I see nothing in that output to suggest that physmap is being used for NAND.

NAND is not directly mapped like NOR is; you cannot just give an address 
range with no knowledge of the controller and expect it to work.

Note that if you look in drivers/mtd/maps/physmap.c, the supported probe 
types are CFI, JEDEC, and ROM.
