  55           The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
  56           You can operate a Linux system on this board by using an M32R
  57           softmacro core, which is a fully-synthesizable functional model
  58           described in Verilog-HDL.
  59
  60           The Mappi-I board was the first platform, which had been used
  61           to port and develop a Linux system for the M32R processor.
  62           Currently, the Mappi-II, an heir to the Mappi-I, is available.
