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

304 machines, but will use only one CPU of a multiprocessor machine. If
305 you say Y here, the kernel will run on many, but not all,

307 will run faster if you say N here.

310 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
