+# GDB support routines for a board using the MIPS remote debugging
+# protocol.  These are actually pretty generic.
+
+# DejaGnu currently assumes that debugging is being done over the main
+# console port.  It would probably be more convenient for people using
+# IDT boards to permit the debugging port and the connected port to be
+# different, since an IDT board has two ports.  This would require
+# extending some of the tests in a fashion similar to that done for
+# VxWorks, because the test output would appear on the other port,
+# rather than being displayed by gdb.
