Hello -- NAND/NOR Flash design for GTA02

[Willie Chen]

Hi Nod, Werner,

Please provide your production information. Werner can't decide the 
NAND/NOR flash partition map here. Thanks.
According GTA02 product specification, we have backup and maintenance 
features. Jserv will also request one partition flash that has erasing 
protection here. There is a another design issue that NOR flash is 
booting uboot and kernel. Or we still use current state that is booting 
from NAND flash.

Regards,
willie
