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

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

288 bool "Preemptible Kernel"
290 This option reduces the latency of the kernel when reacting to
291 real-time or interactive events by allowing a low priority process to
292 be preempted even if it is in kernel mode executing a system call.
293 This allows applications to run more reliably even when the system is

297 or real-time system. Say N if you are unsure.
300 bool "Symmetric multi-processing support"
301 select USE_GENERIC_SMP_HELPERS
303 This enables support for systems with more than one CPU. If you have
304 a system with only one CPU, like most personal computers, say N. If
305 you have a system with more than one CPU, say Y.
307 If you say N here, the kernel will run on single and multiprocessor
308 machines, but will use only one CPU of a multiprocessor machine. If
309 you say Y here, the kernel will run on many, but not all,
310 singleprocessor machines. On a singleprocessor machine, the kernel
311 will run faster if you say N here.
313 People using multiprocessor machines who say Y here should also say
314 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
315 Management" code will be disabled if you say Y here.

337 This is purely to save memory - each supported CPU adds
338 approximately eight kilobytes to the kernel image.

361 menu "Bus options (PCI, PCMCIA, EISA, MCA, ISA)"
368 Find out whether you have a PCI motherboard. PCI is the name of a
369 bus system, i.e. the way the CPU talks to the other stuff inside
370 your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
371 VESA. If you have PCI, say Y, otherwise N.
374 prompt "PCI access mode"
381 On PCI systems, the BIOS can be used to detect the PCI devices and
382 determine their configuration. However, some old PCI motherboards
383 have BIOS bugs and may crash if this is done. Also, some embedded
384 PCI-based systems don't have any BIOS at all. Linux can also try to
385 detect the PCI hardware directly without using the BIOS.
387 With this option, you can specify how Linux should detect the PCI
388 devices. If you choose "BIOS", the BIOS will be used, if you choose
389 "Direct", the BIOS won't be used, and if you choose "Any", the
390 kernel will try the direct access method and falls back to the BIOS
391 if that doesn't work. If unsure, go with the default, which is
