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

 254           This option reduces the latency of the kernel when reacting to

 272           you say Y here, the kernel will run on many, but not all,
