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

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

278 bool "Preemptible Kernel"
280 This option reduces the latency of the kernel when reacting to
281 real-time or interactive events by allowing a low priority process to
282 be preempted even if it is in kernel mode executing a system call.
283 This allows applications to run more reliably even when the system is
286 Say Y here if you are building a kernel for a desktop, embedded
287 or real-time system. Say N if you are unsure.
290 bool "Symmetric multi-processing support"
292 This enables support for systems with more than one CPU. If you have
293 a system with only one CPU, like most personal computers, say N. If
294 you have a system with more than one CPU, say Y.
296 If you say N here, the kernel will run on single and multiprocessor
297 machines, but will use only one CPU of a multiprocessor machine. If
298 you say Y here, the kernel will run on many, but not all,
299 singleprocessor machines. On a singleprocessor machine, the kernel
300 will run faster if you say N here.
302 People using multiprocessor machines who say Y here should also say
303 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
304 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.

350 menu "Bus options (PCI, PCMCIA, EISA, MCA, ISA)"
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.
363 prompt "PCI access mode"
370 On PCI systems, the BIOS can be used to detect the PCI devices and
371 determine their configuration. However, some old PCI motherboards
372 have BIOS bugs and may crash if this is done. Also, some embedded
373 PCI-based systems don't have any BIOS at all. Linux can also try to
374 detect the PCI hardware directly without using the BIOS.
376 With this option, you can specify how Linux should detect the PCI
377 devices. If you choose "BIOS", the BIOS will be used, if you choose
378 "Direct", the BIOS won't be used, and if you choose "Any", the
379 kernel will try the direct access method and falls back to the BIOS
380 if that doesn't work. If unsure, go with the default, which is

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