Thanks a lot for the reply. What I understand from the reply is I need to change my bootcmd environment variable. Currently for loading kernel from NOR, it uses bootm command; now I have to change it to nboot command. Also I understand that I do not need to write a NAND driver for this purpose.
Please confirm if my understanding is correct. By the way, what is the purpose of the code in nand_spl directory?
