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.

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

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

335 This is purely to save memory - each supported CPU adds
336 approximately eight kilobytes to the kernel image.

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

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