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

bool "Preemptible Kernel"
help
This option reduces the latency of the kernel when reacting to
real-time or interactive events by allowing a low priority process to
be preempted even if it is in kernel mode executing a system call.
This allows applications to run more reliably even when the system is
under load.
Say Y here if you are building a kernel for a desktop, embedded
or real-time system. Say N if you are unsure.

---help---
This enables support for systems with more than one CPU. If you have
a system with only one CPU, like most personal computers, say N. If
you have a system with more than one CPU, say Y.
If you say N here, the kernel will run on single and multiprocessor
machines, but will use only one CPU of a multiprocessor machine. If
you say Y here, the kernel will run on many, but not all,
singleprocessor machines. On a singleprocessor machine, the kernel
will run faster if you say N here.
People using multiprocessor machines who say Y here should also say
Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
Management" code will be disabled if you say Y here.
See also the SMP-HOWTO available at
<http://tldp.org/HOWTO/SMP-HOWTO.html>.
If you don't know what to do here, say N.

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

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

---help---
On PCI systems, the BIOS can be used to detect the PCI devices and
determine their configuration. However, some old PCI motherboards
have BIOS bugs and may crash if this is done. Also, some embedded
PCI-based systems don't have any BIOS at all. Linux can also try to
detect the PCI hardware directly without using the BIOS.
With this option, you can specify how Linux should detect the PCI
devices. If you choose "BIOS", the BIOS will be used, if you choose
"Direct", the BIOS won't be used, and if you choose "Any", the
kernel will try the direct access method and falls back to the BIOS
if that doesn't work. If unsure, go with the default, which is
"Any".
