Assuming you have the Xilinx EDK tools installed, there is a program
called xmd that acts as a standalone debugger or can communicate with
gdb over a socket.

EDK builds example programs when you use the BSB.  You can download and
debug these programs as a test.  From EDK 7.1, Tools->Software Debugger.
