  46           The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
  47           You can operate a Linux system on this board by using an M32R
  48           softmacro core, which is a fully-synthesizable functional model
  49           described in Verilog-HDL.
  50
  51           The Mappi-I board was the first platform, which had been used
  52           to port and develop a Linux system for the M32R processor.
  53           Currently, the Mappi-II, an heir to the Mappi-I, is available.

 263           If you say N here, the kernel will run on single and multiprocessor
 264           machines, but will use only one CPU of a multiprocessor machine. If
 265           you say Y here, the kernel will run on many, but not all,
 266           singleprocessor machines. On a singleprocessor machine, the kernel
 267           will run faster if you say N here.
