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

91 The OAKS32R is a tiny, inexpensive evaluation board.
92 Please note that if you say Y here and choose chip "M32102",
93 say N for MMU and select a no-MMU version kernel, otherwise
94 a kernel with MMU support will not work, because the M32102
95 is a microcontroller for embedded systems and it has no MMU.

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

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

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