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

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

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

327 This allows you to specify the maximum number of CPUs which this
328 kernel will support. The maximum supported value is 32 and the
329 minimum value which makes sense is 2.
331 This is purely to save memory - each supported CPU adds
332 approximately eight kilobytes to the kernel image.

355 menu "Bus options (PCI, PCMCIA, EISA, MCA, ISA)"
362 Find out whether you have a PCI motherboard. PCI is the name of a
363 bus system, i.e. the way the CPU talks to the other stuff inside
364 your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
365 VESA. If you have PCI, say Y, otherwise N.
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
