/* INTRODUCTION
The ork1sim has various parameters, that are set in configuration files
like this one. The user can switch between configurations at startup by
specifying the required configuration file with the -f <filename.cfg> option.
If no configuration file is specified or1ksim searches for the default
configuration file sim.cfg. First it searches for './sim.cfg'. If this
file is not found, it searches for '~/or1k/sim.cfg'. If this file is
not found too, it reverts to the built-in default configuration.
NOTE: Users should not rely on the built-in configuration, since the
default configuration may differ between version.
Rather create a configuration file that sets all critical values.
This file may contain (standard C) comments only - no // support.
Configure files may be be included, using:
include "file_name_to_include"
Like normal configuration files, the included file is divided into
sections. Each section is described in detail also.
Some section have subsections. One example of such a subsection is:
device <index>
instance specific parameters...
enddevice
which creates a device instance.

/* MEMORY SECTION
This section specifies how the memory is generated and the blocks
it consists of.

'unknown' does not specify how memory should be generated,
leaving the memory in a undefined state. This is the fastest
option.

The channel parameter indicates the source of received UART characters
and the sink for transmitted UART characters.
The <channeltype> can be either "file", "xterm", "tcp", "fd", or "tty"
(without quotes).
A) To send/receive characters from a pair of files, use a file
channel:
channel=file:<rxfile>,<txfile>
B) To create an interactive terminal window, use an xterm channel:
channel=xterm:[<xterm_arg>]*
C) To create a bidirectional tcp socket which one could, for example,
access via telnet, use a tcp channel:
channel=tcp:<port number>
D) To cause the UART to read/write from existing numeric file
descriptors, use an fd channel:
channel=fd:<rx file descriptor num>,<tx file descriptor num>
E) To connect the UART to a physical serial port, create a tty
channel:
channel=tty:device=/dev/ttyS0,baud=9600
