/* The Ork1sim has various parameters, that can be set in configuration files
   like this one. The user can specify a configuration file at startup with
   the -f <filename.cfg> option.

   The user guide (see the 'doc' directory) gives full details on
   configuration files. This is a reference configuration, which may be used
   as a starting point for customization.

   A number of peripherals are mapped at standard addresses (above 0x80000000)
   in the Verilog RTL of ORPSoC standard sitribution. The same values should
   be used in Or1ksim section definitions to match the behavior of the Verilog
