-/*  timer.c
- *
- *  This file manages the benchmark timer used by the RTEMS Timing Test
- *  Suite.  Each measured time period is demarcated by calls to
- *  Timer_initialize() and Read_timer().  Read_timer() usually returns
- *  the number of microseconds since Timer_initialize() exitted.
- *
- *  This version returns the number of nanoseconds since Timer_initialize() 
- *  exited, since the '604 is very fast at 300MHz.  Actual resolution is
- *  60 nsec.
- *
- *  NOTE: It is important that the timer start/stop overhead be
- *        determined when porting or modifying this code.
