	  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.

	  This enables support for systems with more than one CPU. If you have
	  a system with only one CPU, like most personal computers, say N. If
	  you have a system with more than one CPU, say Y.

	  If you say N here, the kernel will run on single and multiprocessor
	  machines, but will use only one CPU of a multiprocessor machine. If
	  you say Y here, the kernel will run on many, but not all,
	  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
	  Management" code will be disabled if you say Y here.

	  On PCI systems, the BIOS can be used to detect the PCI devices and

	  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
