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.

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.
