I have a NOR Flash used as a boot flash (16MB) and a NAND flash (128MB)to store kernel/rfs on coldfire based custom board . The u-boot is running out of NOR flash but I have problems in enabling NAND support from u-boot. Need clarity on couple of definitions in the board configuration file.
CFG_FLASH_SIZE : Should it include both NOR+NAND size
CFG_MAX_FLASH_BANKS: If there are two flash devices, is it correct to give as 2. Is NAND flash identified as a seperate Bank.
CFG_FLASH_BANKS_LIST : Should it include both Flash base addresses.
Welcome any other pointers when working with both NOR/NAND Flash.
Thanks in adv.

CFG_FLASH_SIZE : CFG_MAX_FLASH_BANKS: CFG_FLASH_BANKS_LIST :
these defines have nothing to do with NAND -mike
