Update of /cvsroot/src/sys/arch/mips/mips
In directory nb00:/tmp/cvs-serv13967/mips/mips

Modified Files:
        locore_r4000.S 
Log Message:
Add locore assembler functions to read mips3 cycle counter, and
read and write compare register (controls cycle-driven periodic interrupt).

Use cycle counter for microsecond time on mips3, but for now only on
3min motherboards (5000/150).  the MAXINE baseboard microsecond
counter is more stable and I don't ave no 5000/260 to test.

XXX clkread() is a mess, it should be rewritten.
XXX should add nanotime() to give inkernel nanosecond resolution,
    and then microtime() reworked to use nanotime().
