+ * Copyright (C) 1996 Paul Mackerras.
+ * Copyright (C) 2000 Dan Malek.
+ * Quick hack of Paul's code to make XMON work on 8xx processors.  Lots
+ * of assumptions, like the SMC1 is used, it has been initialized by the
+ * loader at some point, and we can just stuff and suck bytes.
+ * We rely upon the 8xx uart driver to support us, as the interface
+ * changes between boot up and operational phases of the kernel.
