  59           The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
  60           You can operate a Linux system on this board by using an M32R
  61           softmacro core, which is a fully-synthesizable functional model
  62           described in Verilog-HDL.
  63
  64           The Mappi-I board was the first platform, which had been used
  65           to port and develop a Linux system for the M32R processor.
  66           Currently, the Mappi-II, an heir to the Mappi-I, is available.
