-/*  timer.c
- *
- *  This file manages the interval timer on the PowerPC MPC821.
- *  NOTE: This is not the PIT, but rather the RTEMS interval
- *        timer
- *  We shall use the bottom 32 bits of the timebase register,
- *
- *  The following was in the 403 version of this file. I don't
- *  know what it means. JTM 5/19/98
- *  NOTE: It is important that the timer start/stop overhead be
- *        determined when porting or modifying this code.
