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.

83 The M3T-M32104UT is an reference board based on uT-Engine
84 specification. This board has a M32104 chip.

222 bool "Preemptible Kernel"
224 This option reduces the latency of the kernel when reacting to
225 real-time or interactive events by allowing a low priority process to
226 be preempted even if it is in kernel mode executing a system call.
227 This allows applications to run more reliably even when the system is
230 Say Y here if you are building a kernel for a desktop, embedded
231 or real-time system. Say N if you are unsure.
234 bool "Symmetric multi-processing support"
236 This enables support for systems with more than one CPU. If you have
237 a system with only one CPU, like most personal computers, say N. If
238 you have a system with more than one CPU, say Y.
240 If you say N here, the kernel will run on single and multiprocessor
241 machines, but will use only one CPU of a multiprocessor machine. If
242 you say Y here, the kernel will run on many, but not all,
243 singleprocessor machines. On a singleprocessor machine, the kernel
244 will run faster if you say N here.
246 People using multiprocessor machines who say Y here should also say
247 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
248 Management" code will be disabled if you say Y here.
250 See also the <file:Documentation/smp.txt>,

267 This allows you to specify the maximum number of CPUs which this
268 kernel will support. The maximum supported value is 32 and the
269 minimum value which makes sense is 2.
271 This is purely to save memory - each supported CPU adds
272 approximately eight kilobytes to the kernel image.

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

352 name of a bus system, i.e. the way the CPU talks to the other stuff
