Hello,

Please find attached the sim patches that allow to get a basic OpenRISC
system running. This was used to verify the OpenRISC gdb port.

The main author is Peter Gavin who should have his FSF copyright in place.

Request for comments on:
- The testcase has a few tests commented out. I do not plan to fix now,
but hopefully be addressed after upstreaming.

# Test Results #

Sim dejagnu tests were added specifically for openrisc and used to test
this. Please see the details of running the testsuite for sim below:
