  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.
  43
  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.

 240           This option reduces the latency of the kernel when reacting to

 242           be preempted even if it is in kernel mode executing a system call.
 243           This allows applications to run more reliably even when the system is

 255
 256           If you say N here, the kernel will run on single and multiprocessor
 257           machines, but will use only one CPU of a multiprocessor machine. If
 258           you say Y here, the kernel will run on many, but not all,
 259           singleprocessor machines. On a singleprocessor machine, the kernel
 260           will run faster if you say N here.
 261
 262           People using multiprocessor machines who say Y here should also say

 338           have BIOS bugs and may crash if this is done. Also, some embedded
 339           PCI-based systems don't have any BIOS at all. Linux can also try to
