/*-----------------------------------------------------------------------------
   This version for the OpenRISC 1000 architecture is a rewrite by Jeremy
   Bennett of the old GDB 5.3 interface to make use of gdbarch for GDB 6.8.
 
   The code tries to follow the GDB coding style. All OR1K specific globals
   should have names beginning ork1_ or OR1K_.
 
   Commenting is Doxygen compatible.
 
   Much has been stripped out. See the files or1k-tdep.c, remote-or1k.c and
   or1k-jtag.c for details of what has changed.
