  67           The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
  68           You can operate a Linux system on this board by using an M32R
  69           softmacro core, which is a fully-synthesizable functional model
  70           described in Verilog-HDL.
  71
  72           The Mappi-I board was the first platform, which had been used
  73           to port and develop a Linux system for the M32R processor.
  74           Currently, the Mappi-II, an heir to the Mappi-I, is available.
