	  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.

	  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.
