245 traditional 68K parts, and on all ColdFire parts you need to set

255 Define the CPU clock frequency in use. This is the core clock
256 frequency, it may or may not be the same as the external clock
257 crystal fitted to your board. Some processors have an internal
258 PLL and can have their frequency programmed at run time, others

638 comment "RAM configuration"
641 hex "Address of the base of RAM"
644 Define the address that RAM starts at. On many platforms this is
645 0, the base of the address space. And this is the default. Some
646 platforms choose to setup their RAM at other addresses within the
647 processor address space.
650 hex "Size of RAM (in bytes), or 0 for automatic"
653 Define the size of the system RAM. If you select 0 then the
654 kernel will try to probe the RAM size at runtime. This is not
655 supported on all CPU types.
658 hex "Address of the base of system vectors"
661 Define the address of the system vectors. Commonly this is
662 put at the start of RAM, but it doesn't have to be. On ColdFire
663 platforms this address is programmed into the VBR register, thus
664 actually setting the address to use.
667 hex "Address of the MBAR (internal peripherals)"
671 Define the address of the internal system peripherals. This value
672 is set in the processors MBAR register. This is generally setup by
673 the boot loader, and will not be written by the kernel. By far most
674 ColdFire boards use the default 0x10000000 value, so if unsure then
678 hex "Address of the IPSBAR (internal peripherals)"
680 depends on HAVE_IPSBAR
682 Define the address of the internal system peripherals. This value
683 is set in the processors IPSBAR register. This is generally setup by
684 the boot loader, and will not be written by the kernel. By far most
685 ColdFire boards use the default 0x40000000 value, so if unsure then
689 hex "Address of the base of kernel code"
692 Typically on m68k systems the kernel will not start at the base
693 of RAM, but usually some small offset from it. Define the start
694 address of the kernel here. The most common setup will have the
695 processor vectors at the base of RAM and then the start of the
696 kernel. On some platforms some RAM is reserved for boot loaders
697 and the kernel starts after that. The 0x400 default was based on
698 a system with the RAM based at address 0, and leaving enough room
699 for the theoretical maximum number of 256 vectors.
702 prompt "RAM bus width"
708 Select the physical RAM data bus size. Not needed on most platforms,
709 so you can generally choose AUTO.
714 Configure RAM bus to be 8 bits wide.
719 Configure RAM bus to be 16 bits wide.
724 Configure RAM bus to be 32 bits wide.
728 comment "ROM configuration"
731 bool "Specify ROM linker regions"
734 Define a ROM region for the linker script. This creates a kernel
735 that can be stored in flash, with possibly the text, and data
736 regions being copied out to RAM at startup.
739 hex "Address of the base of ROM device"
743 Define the address that the ROM region starts at. Some platforms
744 use this to set their chip select region accordingly for the boot
748 hex "Address of the base of the ROM vectors"
752 This is almost always the same as the base of the ROM. Since on all
753 68000 type variants the vectors are at the base of the boot device
757 hex "Size of ROM vector region (in bytes)"
761 Define the size of the vector region in ROM. For most 68000
762 variants this would be 0x400 bytes in size. Set to 0 if you do
763 not want a vector region at the start of the ROM.
766 hex "Address of the base of system image in ROM"
770 Define the start address of the system image in ROM. Commonly this
771 is strait after the ROM vectors.
774 hex "Size of the ROM device"
778 Size of the ROM device. On some platforms this is used to setup
779 the chip select that controls the boot ROM device.
782 prompt "Kernel executes from"
784 Choose the memory type that the kernel will be running in.
789 The kernel will be resident in RAM when running.
794 The kernel will be resident in FLASH/ROM when running. This is
795 often referred to as Execute-in-Place (XIP), since the kernel
796 code executes from the position it is stored in the FLASH/ROM.
