For example, 1. I only want to let end user to flash normal part [0-384k), and don't let him touch fallback part [384k, 512k). 2. or I only want to update the payload image in the beginning, [0,64k).

Ollie or David,
Can you modify the flash_rom to take start and size command line?
I mean
Flash_rom -start=0k -size=384k xxxx.rom
And xxxx.rom only to be 384k.
Why do you want to do this ? You should prepare the image the same size as your flash chip.
There are techinical difficulty doing this. Most flash parts are block/sector erase and byte program. There is no general way to start from an abitrary address to any size.
