          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.

          say N for MMU and select a no-MMU version kernel, otherwise
          a kernel with MMU support will not work, because the M32102

config PREEMPT
        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.

config SMP
        bool "Symmetric multi-processing support"
        ---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 <file:Documentation/smp.txt>,
          and the SMP-HOWTO available at
          <http://www.linuxdoc.org/docs.html#howto>.

          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.

          On PCI systems, the BIOS can be used to detect the PCI devices and

          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
