Thanks, now it's a bit easier to find my way around the deep jungles
of U-Boot :-)

Would you please elaborate on my previous statement:

>> So the settings as follows mainly refer to NOR:
>> CFG_MAX_FLASH_BANKS
>> CFG_NO_FLASH
>> CFG_MAX_FLASH_BANKS_DETECT
>> CFG_FLASH_BASE
>> CFG_FLASH_ERASE_TOUT
>> CFG_FLASH_WRITE_TOUT
>> CFG_FLASH_LOCK_TOUT
>> CFG_FLASH_UNLOCK_TOUT

>> while
>> CFG_MAX_NAND_DEVICE
>> CFG_NAND_SELECT_DEVICE

>> are NAND-related

Is my understanding correct, if not - why?
Thanks again.
