-/*************************************************************************
- * Timer handling for EP93xx
- *************************************************************************
- * The ep93xx has four internal timers. Timers 1, 2 (both 16 bit) and
- * 3 (32 bit) count down at 508 kHz, are self-reloading, and can generate
- * an interrupt on underflow. Timer 4 (40 bit) counts down at 983.04 kHz,
- * is free-running, and can't generate interrupts.
- *
- * The 508 kHz timers are ideal for use for the timer interrupt, as the
- * most common values of HZ divide 508 kHz nicely. We pick the 32 bit
- * timer (timer 3) to get as long sleep intervals as possible when using
- * CONFIG_NO_HZ.
- *
- * The higher clock rate of timer 4 makes it a better choice than the
- * other timers for use as clock source and for sched_clock(), providing
- * a stable 40 bit time base.
