/* INTRODUCTION

   The or1ksim have various parameters, which can be set in configuration
   files.  Multiple configurations may be used and switched between at
   or1ksim startup.
   By default, or1ksim loads condfiguration file from './sim.cfg' and if not
   found it checks '~/.or1k/sim.cfg'. If even this file is not found or
   all parameters are not defined, default configuration is used.
   Users should not rely on default configuration, but rather redefine all
   critical settings, since default configuration may differ in newer
   versions of the or1ksim.
   If multiple configurations are used, user can switch between them by
   supplying -f <filename.cfg> option when starting simulator.

   This file may contain (standard C) only comments - no // support.
   
   Configure files can also be included, using:
   
   include "file_name_to_include"

   Like normal configuration file, this file is divided in sections,
   where each section is described in detail also.

   Some section also have subsections. One example of such subsection is
   block:

   device <index>
     instance specific parameters...
   enddevice

   which creates a device instance.

/* MEMORY SECTION

   This section specifies how is initial memory generated and which blocks
   it consist of.

   type = random/unknown/pattern
      specifies the initial memory values. 'random' parameter generate
      random memory using seed 'random_seed' parameter. 'pattern' parameter
      fills memory with 'pattern' parameter and 'unknown' does not specify
      how memory should be generated - the fastest option.

        0, if this device is uart 16450 and 1, if it is 16550
