http://perforce.freebsd.org/chv.cgi?CH=101570 Change 101570 by bms@bms_montagne on 2006/07/14 16:17:47 Add a basic timecounter wrapper for the MIPS32 Count register so we can tell the time. Depends on a deterministic DELAY() for calibration, which I haven't done yet. While we're here update clock.h to what is needed for mips.
