	  on the VM subsystem for higher order allocations.

comment "RAM configuration"

config RAMBASE
	hex "Address of the base of RAM"
	default "0"
	help
	  Define the address that RAM starts at. On many platforms this is
	  0, the base of the address space. And this is the default. Some
	  platforms choose to setup their RAM at other addresses within the
	  processor address space.

config RAMSIZE
	hex "Size of RAM (in bytes), or 0 for automatic"
	default "0x400000"
	help
	  Define the size of the system RAM. If you select 0 then the
	  kernel will try to probe the RAM size at runtime. This is not
	  supported on all CPU types.

config VECTORBASE
	hex "Address of the base of system vectors"
	default "0"
	help
	  Define the address of the system vectors. Commonly this is
	  put at the start of RAM, but it doesn't have to be. On ColdFire
	  platforms this address is programmed into the VBR register, thus
	  actually setting the address to use.

config MBAR
	hex "Address of the MBAR (internal peripherals)"
	default "0x10000000"
	depends on HAVE_MBAR
	help
	  Define the address of the internal system peripherals. This value
	  is set in the processors MBAR register. This is generally setup by
	  the boot loader, and will not be written by the kernel. By far most
	  ColdFire boards use the default 0x10000000 value, so if unsure then
	  use this.

config IPSBAR
	hex "Address of the IPSBAR (internal peripherals)"
	default "0x40000000"
	depends on HAVE_IPSBAR
	help
	  Define the address of the internal system peripherals. This value
	  is set in the processors IPSBAR register. This is generally setup by
	  the boot loader, and will not be written by the kernel. By far most
	  ColdFire boards use the default 0x40000000 value, so if unsure then
	  use this.

config KERNELBASE
	hex "Address of the base of kernel code"
	default "0x400"
	help
	  Typically on m68k systems the kernel will not start at the base
	  of RAM, but usually some small offset from it. Define the start
	  address of the kernel here. The most common setup will have the
	  processor vectors at the base of RAM and then the start of the
	  kernel. On some platforms some RAM is reserved for boot loaders
	  and the kernel starts after that. The 0x400 default was based on
	  a system with the RAM based at address 0, and leaving enough room
	  for the theoretical maximum number of 256 vectors.

comment "ROM configuration"

config ROM
	bool "Specify ROM linker regions"
	help
	  Define a ROM region for the linker script. This creates a kernel
	  that can be stored in flash, with possibly the text, and data
	  regions being copied out to RAM at startup.

config ROMBASE
	hex "Address of the base of ROM device"
	default "0"
	depends on ROM
	help
	  Define the address that the ROM region starts at. Some platforms
	  use this to set their chip select region accordingly for the boot
	  device.

config ROMVEC
	hex "Address of the base of the ROM vectors"
	default "0"
	depends on ROM
	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 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.

choice
	prompt "Kernel executes from"
	---help---
	  Choose the memory type that the kernel will be running in.

config RAMKERNEL
	bool "RAM"
	help
	  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.
