/*
* Debugging macros
*
* The DPRINTF macro can be used by setting the debug_print_level to the
* appropriate debugging level. The debug levels are defined in each source
* file where this header file is included. The scoping of debug_info,
* and debug_print_level is to the file which included the header file.
* If multiple levels need to be output, the values can be 'ored'
* together into debug_print_level. If debug_print_line's bit 1 is set, the
* line number of the debugging statement is printed out. If it has
* bit 2 set, the macro will drop into either the debugger or the OBP PROM.
