Author: ian Date: Mon Oct 20 23:32:34 2014 New Revision: 273352 URL: https://svnweb.freebsd.org/changeset/base/273352 Log: The imx6 hardware is fast enough to make good use of however much timecounter resolution is available, so ask for a 1 GHz frequency. It won't actually get one that fast, but that'll get the fastest available clock and use a divisor of 1 (probably 132 or 66mhz on current hardware).
