Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

43 The Mappi-I is an FPGA board for SOC (System-On-a-Chip) prototyping.
44 You can operate a Linux system on this board by using an M32R
45 softmacro core, which is a fully-synthesizable functional model
46 described in Verilog-HDL.
47
48 The Mappi-I board was the first platform, which had been used
49 to port and develop a Linux system for the M32R processor.
50 Currently, the Mappi-II, an heir to the Mappi-I, is available.

207 This option reduces the latency of the kernel when reacting to
208 real-time or interactive events by allowing a low priority process to
209 be preempted even if it is in kernel mode executing a system call.
210 This allows applications to run more reliably even when the system is
211 under load.

226 you have a system with more than one CPU, say Y.
227
228 If you say N here, the kernel will run on single and multiprocessor
229 machines, but will use only one CPU of a multiprocessor machine. If
230 you say Y here, the kernel will run on many, but not all,
231 singleprocessor machines. On a singleprocessor machine, the kernel
232 will run faster if you say N here.
233
234 People using multiprocessor machines who say Y here should also say
235 Y to "Enhanced Real Time Clock Support", below. The "Advanced Power
236 Management" code will be disabled if you say Y here.

301 ---help---
302 On PCI systems, the BIOS can be used to detect the PCI devices and
303 determine their configuration. However, some old PCI motherboards
304 have BIOS bugs and may crash if this is done. Also, some embedded
305 PCI-based systems don't have any BIOS at all. Linux can also try to
306 detect the PCI hardware directly without using the BIOS.
307
308 With this option, you can specify how Linux should detect the PCI
309 devices. If you choose "BIOS", the BIOS will be used, if you choose
310 "Direct", the BIOS won't be used, and if you choose "Any", the
311 kernel will try the direct access method and falls back to the BIOS
312 if that doesn't work. If unsure, go with the default, which is
313 "Any".
