config PLAT_MAPPI
	bool "Mappi-I"
	help
	  The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
	  You can operate a Linux system on this board by using an M32R
	  softmacro core, which is a fully-synthesizable functional model
	  described in Verilog-HDL.

	  The Mappi-I board was the first platform, which had been used
	  to port and develop a Linux system for the M32R processor.
	  Currently, the Mappi-II, an heir to the Mappi-I, is available.

	  You can say Y for SMP, because the M32700 is a single chip

	  Please note that if you say Y here and choose chip "M32102",
	  say N for MMU and select a no-MMU version kernel, otherwise
	  a kernel with MMU support will not work, because the M32102
	  is a microcontroller for embedded systems and it has no MMU.

	  This enables support for systems with more than one CPU. If you have

	  you have a system with more than one CPU, say Y.

	  If you say N here, the kernel will run on single and multiprocessor

	  singleprocessor machines. On a singleprocessor machine, the kernel
	  will run faster if you say N here.

	  People using multiprocessor machines who say Y here should also say
	  Y to "Enhanced Real Time Clock Support", below. The "Advanced Power

	  See also the <file:Documentation/smp.txt>,

	  bus system, i.e. the way the CPU talks to the other stuff inside
	  your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
	  VESA. If you have PCI, say Y, otherwise N.

	  The PCI-HOWTO, available from

	---help---
	  On PCI systems, the BIOS can be used to detect the PCI devices and
	  determine their configuration. However, some old PCI motherboards
	  have BIOS bugs and may crash if this is done. Also, some embedded
	  PCI-based systems don't have any BIOS at all. Linux can also try to
	  detect the PCI hardware directly without using the BIOS.

	  With this option, you can specify how Linux should detect the PCI
	  devices. If you choose "BIOS", the BIOS will be used, if you choose
	  "Direct", the BIOS won't be used, and if you choose "Any", the
	  kernel will try the direct access method and falls back to the BIOS
	  if that doesn't work. If unsure, go with the default, which is
	  "Any".

	318	---help---
	319	On PCI systems, the BIOS can be used to detect the PCI devices and
	320	determine their configuration. However, some old PCI motherboards
	321	have BIOS bugs and may crash if this is done. Also, some embedded
	322	PCI-based systems don't have any BIOS at all. Linux can also try to
	323	detect the PCI hardware directly without using the BIOS.
	324
	325	With this option, you can specify how Linux should detect the PCI
	326	devices. If you choose "BIOS", the BIOS will be used, if you choose
	327	"Direct", the BIOS won't be used, and if you choose "Any", the
	328	kernel will try the direct access method and falls back to the BIOS
	329	if that doesn't work. If unsure, go with the default, which is
