200 crystal fitted to your board. Some processors have an internal
201 PLL and can have their frequency programmed at run time, others

571 If you say Y here the kernel will use a 4Kb stacksize for the

574 on the VM subsystem for higher order allocations.
576 comment "RAM configuration"
579 hex "Address of the base of RAM"
582 Define the address that RAM starts at. On many platforms this is
583 0, the base of the address space. And this is the default. Some
584 platforms choose to setup their RAM at other addresses within the
585 processor address space.
588 hex "Size of RAM (in bytes), or 0 for automatic"
591 Define the size of the system RAM. If you select 0 then the
592 kernel will try to probe the RAM size at runtime. This is not
593 supported on all CPU types.
596 hex "Address of the base of system vectors"
599 Define the address of the system vectors. Commonly this is
600 put at the start of RAM, but it doesn't have to be. On ColdFire
601 platforms this address is programmed into the VBR register, thus
602 actually setting the address to use.
605 hex "Address of the MBAR (internal peripherals)"
609 Define the address of the internal system peripherals. This value
610 is set in the processors MBAR register. This is generally setup by
611 the boot loader, and will not be written by the kernel. By far most
612 ColdFire boards use the default 0x10000000 value, so if unsure then
616 hex "Address of the IPSBAR (internal peripherals)"
618 depends on HAVE_IPSBAR
620 Define the address of the internal system peripherals. This value
621 is set in the processors IPSBAR register. This is generally setup by
622 the boot loader, and will not be written by the kernel. By far most
623 ColdFire boards use the default 0x40000000 value, so if unsure then
627 hex "Address of the base of kernel code"
630 Typically on m68k systems the kernel will not start at the base
631 of RAM, but usually some small offset from it. Define the start
632 address of the kernel here. The most common setup will have the
633 processor vectors at the base of RAM and then the start of the
634 kernel. On some platforms some RAM is reserved for boot loaders
635 and the kernel starts after that. The 0x400 default was based on
636 a system with the RAM based at address 0, and leaving enough room
637 for the theoretical maximum number of 256 vectors.
640 prompt "RAM bus width"
646 Select the physical RAM data bus size. Not needed on most platforms,
647 so you can generally choose AUTO.
652 Configure RAM bus to be 8 bits wide.
657 Configure RAM bus to be 16 bits wide.
662 Configure RAM bus to be 32 bits wide.
666 comment "ROM configuration"
669 bool "Specify ROM linker regions"
672 Define a ROM region for the linker script. This creates a kernel
673 that can be stored in flash, with possibly the text, and data
674 regions being copied out to RAM at startup.
677 hex "Address of the base of ROM device"
681 Define the address that the ROM region starts at. Some platforms
682 use this to set their chip select region accordingly for the boot
686 hex "Address of the base of the ROM vectors"
690 This is almost always the same as the base of the ROM. Since on all
691 68000 type variants the vectors are at the base of the boot device
695 hex "Size of ROM vector region (in bytes)"
699 Define the size of the vector region in ROM. For most 68000
700 variants this would be 0x400 bytes in size. Set to 0 if you do
701 not want a vector region at the start of the ROM.
704 hex "Address of the base of system image in ROM"
708 Define the start address of the system image in ROM. Commonly this
709 is strait after the ROM vectors.
712 hex "Size of the ROM device"
716 Size of the ROM device. On some platforms this is used to setup
717 the chip select that controls the boot ROM device.
720 prompt "Kernel executes from"
722 Choose the memory type that the kernel will be running in.
727 The kernel will be resident in RAM when running.
732 The kernel will be resident in FLASH/ROM when running. This is
733 often referred to as Execute-in-Place (XIP), since the kernel
734 code executes from the position it is stored in the FLASH/ROM.
