43 The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
44 You can operate a Linux system on this board by using an M32R
45 softmacro core, which is a fully-synthesizable functional model
46 described in Verilog-HDL.
47
48 The Mappi-I board was the first platform, which had been used
49 to port and develop a Linux system for the M32R processor.
50 Currently, the Mappi-II, an heir to the Mappi-I, is available.

74 say N for MMU and select a no-MMU version kernel, otherwise
75 a kernel with MMU support will not work, because the M32102

243 help
244 This option reduces the latency of the kernel when reacting to
245 real-time or interactive events by allowing a low priority process to
246 be preempted even if it is in kernel mode executing a system call.
247 This allows applications to run more reliably even when the system is
248 under load.

251 or real-time system. Say N if you are unsure.

256 This enables support for systems with more than one CPU. If you have
257 a system with only one CPU, like most personal computers, say N. If
258 you have a system with more than one CPU, say Y.
259
260 If you say N here, the kernel will run on single and multiprocessor
261 machines, but will use only one CPU of a multiprocessor machine. If
262 you say Y here, the kernel will run on many, but not all,
263 singleprocessor machines. On a singleprocessor machine, the kernel
264 will run faster if you say N here.
265
266 People using multiprocessor machines who say Y here should also say
267 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
268 Management" code will be disabled if you say Y here.

339 ---help---
340 On PCI systems, the BIOS can be used to detect the PCI devices and
341 determine their configuration. However, some old PCI motherboards
342 have BIOS bugs and may crash if this is done. Also, some embedded
343 PCI-based systems don't have any BIOS at all. Linux can also try to
344 detect the PCI hardware directly without using the BIOS.
345
346 With this option, you can specify how Linux should detect the PCI
347 devices. If you choose "BIOS", the BIOS will be used, if you choose
348 "Direct", the BIOS won't be used, and if you choose "Any", the
349 kernel will try the direct access method and falls back to the BIOS
350 if that doesn't work. If unsure, go with the default, which is
