hello i run modified version of at91rm9200dk, without on-board 2mb flash. u-boot code 'detects' it as as 0-bytes flash chip at address 0 (so it seems find). but since addr2info function checks against address+size-1 it becomes 0xffffffff. i think this patch won't hurt ;)

This patch might be a good idea, but I think you're just fixing a symptom here. A 0 length region shouldn't be registered in flash_info in the first place. You should look for the root cause.
