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

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

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

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

326 This allows you to specify the maximum number of CPUs which this

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

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