        help

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

          68000 type variants the vectors are at the base of the boot device

          on system startup.

config ROMVECSIZE

        hex "Size of ROM vector region (in bytes)"

        default "0x400"

        depends on ROM

        help

          Define the size of the vector region in ROM. For most 68000

          variants this would be 0x400 bytes in size. Set to 0 if you do

          not want a vector region at the start of the ROM.

config ROMSTART

        hex "Address of the base of system image in ROM"

        default "0x400"

        depends on ROM

        help

          Define the start address of the system image in ROM. Commonly this

          is strait after the ROM vectors.

config ROMSIZE

        hex "Size of the ROM device"

        default "0x100000"

        depends on ROM

        help

          Size of the ROM device. On some platforms this is used to setup

          the chip select that controls the boot ROM device.

          The kernel will be resident in RAM when running.

config ROMKERNEL

        bool "ROM"

        help

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

          often referred to as Execute-in-Place (XIP), since the kernel

          code executes from the position it is stored in the FLASH/ROM.
