I was thinking of the NOR flash as a backup if everithing goes wrong. If you flashed the NAND with a new bootloader and it fails you maybe couldn't start the bootloader from NAND anymore. But you always could boot from NOR flash because you couldn't/didn't reflash this bootloader. Maybe i'm totaly wrong about the duty of the NOR flash, but this is what i think of it. It is the life belt if you swim too far out of the "NAND flashing" sea. :)
