560 | Define a ROM region for the linker script. This creates a kernel | |

578 | This is almost always the same as the base of the ROM. Since on all | |

587 | Define the size of the vector region in ROM. For most 68000 | |
588 | variants this would be 0x400 bytes in size. Set to 0 if you do | |

620 | The kernel will be resident in FLASH/ROM when running. This is | |
