39 | The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping. | |
40 | You can operate a Linux system on this board by using an M32R | |
41 | softmacro core, which is a fully-synthesizable functional model | |
42 | described in Verilog-HDL. | |
43 | ||
44 | The Mappi-I board was the first platform, which had been used | |
45 | to port and develop a Linux system for the M32R processor. | |
46 | Currently, the Mappi-II, an heir to the Mappi-I, is available. | |

236 | under load. | |

246 | you have a system with more than one CPU, say Y. | |
247 | ||
248 | If you say N here, the kernel will run on single and multiprocessor | |
249 | machines, but will use only one CPU of a multiprocessor machine. If | |
250 | you say Y here, the kernel will run on many, but not all, | |
251 | singleprocessor machines. On a singleprocessor machine, the kernel | |
252 | will run faster if you say N here. | |
253 | ||
254 | People using multiprocessor machines who say Y here should also say | |
255 | Y to "Enhanced Real Time Clock Support", below. The "Advanced Power | |
