638      Define the address that the ROM region starts at. Some platforms
639      use this to set their chip select region accordingly for the boot
640      device.

645    depends on ROM
646    help
647      This is almost always the same as the base of the ROM. Since on all
648      68000 type variants the vectors are at the base of the boot device
649      on system startup.

651config ROMVECSIZE

654    depends on ROM
655    help
656      Define the size of the vector region in ROM. For most 68000
657      variants this would be 0x400 bytes in size. Set to 0 if you do
658      not want a vector region at the start of the ROM.

665      Define the start address of the system image in ROM. Commonly this
666      is strait after the ROM vectors.

688    help
689      The kernel will be resident in FLASH/ROM when running. This is
690      often referred to as Execute-in-Place (XIP), since the kernel
691      code executes from the position it is stored in the FLASH/ROM.
