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