39 The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
40 You can operate a Linux system on this board by using an M32R
41 softmacro core, which is a fully-synthesizable functional model
42 described in Verilog-HDL.
44 The Mappi-I board was the first platform, which had been used
45 to port and develop a Linux system for the M32R processor.
46 Currently, the Mappi-II, an heir to the Mappi-I, is available.
54 The M3T-M32700UT is an evaluation board based on uT-Engine
55 specification. This board has an M32700 (Chaos) evaluation chip.
56 You can say Y for SMP, because the M32700 is a single chip
62 The OPSPUT is an evaluation board based on uT-Engine
63 specification. This board has a OPSP-REP chip.
68 The OAKS32R is a tiny, inexpensive evaluation board.
69 Please note that if you say Y here and choose chip "M32102",
70 say N for MMU and select a no-MMU version kernel, otherwise
71 a kernel with MMU support will not work, because the M32102
72 is a microcontroller for embedded systems and it has no MMU.

201 bool "Preemptible Kernel"
203 This option reduces the latency of the kernel when reacting to
204 real-time or interactive events by allowing a low priority process to
205 be preempted even if it is in kernel mode executing a system call.
206 This allows applications to run more reliably even when the system is
209 Say Y here if you are building a kernel for a desktop, embedded
210 or real-time system. Say N if you are unsure.
214 depends on (SMP || PREEMPT)
218 bool "Symmetric multi-processing support"
220 This enables support for systems with more than one CPU. If you have
221 a system with only one CPU, like most personal computers, say N. If
222 you have a system with more than one CPU, say Y.
224 If you say N here, the kernel will run on single and multiprocessor
225 machines, but will use only one CPU of a multiprocessor machine. If
226 you say Y here, the kernel will run on many, but not all,
227 singleprocessor machines. On a singleprocessor machine, the kernel
228 will run faster if you say N here.
230 People using multiprocessor machines who say Y here should also say
231 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
232 Management" code will be disabled if you say Y here.

246 int "Maximum number of CPUs (2-32)"
251 This allows you to specify the maximum number of CPUs which this
252 kernel will support. The maximum supported value is 32 and the
253 minimum value which makes sense is 2.
255 This is purely to save memory - each supported CPU adds
256 approximately eight kilobytes to the kernel image.

280 Find out whether you have a PCI motherboard. PCI is the name of a
281 bus system, i.e. the way the CPU talks to the other stuff inside
282 your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
283 VESA. If you have PCI, say Y, otherwise N.
285 The PCI-HOWTO, available from
286 <http://www.linuxdoc.org/docs.html#howto>, contains valuable
287 information about which PCI hardware does work under Linux and which
291 prompt "PCI access mode"
298 On PCI systems, the BIOS can be used to detect the PCI devices and
299 determine their configuration. However, some old PCI motherboards
300 have BIOS bugs and may crash if this is done. Also, some embedded
301 PCI-based systems don't have any BIOS at all. Linux can also try to
302 detect the PCI hardware directly without using the BIOS.
304 With this option, you can specify how Linux should detect the PCI
305 devices. If you choose "BIOS", the BIOS will be used, if you choose
306 "Direct", the BIOS won't be used, and if you choose "Any", the
307 kernel will try the direct access method and falls back to the BIOS
308 if that doesn't work. If unsure, go with the default, which is

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