I use the fallback and the normal mode, if my chip has a size 256*1024,
what  size of FALLBACK_SIZE and ROM_IMAGE_SIZE I can choose, I have some
difficulty to define the role of the ROM_IMAGE_SIZE, the ROM_SIZE define
the  size of the chip, the FALLBACK_SIZE define the size of the fallback
mode, but the ROM_IMAGE_SIZE ??? I don't understand the goal of
ROM_IMAGE_SIZE, if you have an better explaination that on the Web site, I
would appreciate much.

Thanks by advance for your help.
