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

86 Please note that if you say Y here and choose chip "M32102",
87 say N for MMU and select a no-MMU version kernel, otherwise
88 a kernel with MMU support will not work, because the M32102
89 is a microcontroller for embedded systems and it has no MMU.

277 bool "Preemptible Kernel"
279 This option reduces the latency of the kernel when reacting to
280 real-time or interactive events by allowing a low priority process to
281 be preempted even if it is in kernel mode executing a system call.
282 This allows applications to run more reliably even when the system is
285 Say Y here if you are building a kernel for a desktop, embedded
286 or real-time system. Say N if you are unsure.
289 bool "Symmetric multi-processing support"
291 This enables support for systems with more than one CPU. If you have
292 a system with only one CPU, like most personal computers, say N. If
293 you have a system with more than one CPU, say Y.
295 If you say N here, the kernel will run on single and multiprocessor
296 machines, but will use only one CPU of a multiprocessor machine. If
297 you say Y here, the kernel will run on many, but not all,
298 singleprocessor machines. On a singleprocessor machine, the kernel
299 will run faster if you say N here.
301 People using multiprocessor machines who say Y here should also say
302 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
303 Management" code will be disabled if you say Y here.

324 minimum value which makes sense is 2.
326 This is purely to save memory - each supported CPU adds
327 approximately eight kilobytes to the kernel image.

357 Find out whether you have a PCI motherboard. PCI is the name of a
358 bus system, i.e. the way the CPU talks to the other stuff inside
359 your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
360 VESA. If you have PCI, say Y, otherwise N.
362 The PCI-HOWTO, available from
363 <http://www.linuxdoc.org/docs.html#howto>, contains valuable
364 information about which PCI hardware does work under Linux and which
368 prompt "PCI access mode"
375 On PCI systems, the BIOS can be used to detect the PCI devices and
376 determine their configuration. However, some old PCI motherboards
377 have BIOS bugs and may crash if this is done. Also, some embedded
378 PCI-based systems don't have any BIOS at all. Linux can also try to
379 detect the PCI hardware directly without using the BIOS.
381 With this option, you can specify how Linux should detect the PCI
382 devices. If you choose "BIOS", the BIOS will be used, if you choose
383 "Direct", the BIOS won't be used, and if you choose "Any", the
384 kernel will try the direct access method and falls back to the BIOS
385 if that doesn't work. If unsure, go with the default, which is

412 name of a bus system, i.e. the way the CPU talks to the other stuff
413 inside your box. If you have ISA, say Y, otherwise N.
