Implement a clkread() function for microtime() using a multu/mfhi
...
sequence using the reciprocal of the delay divisor to perform the
division.
Set the cp0 compare register so that it doesn't trigger interrupts and
reset the cp0 count register in the hardclock interrupt handler.

Calculate the reciprocal of the divisor delay. From the comments:
...
To implement a more accurate microtime using the CP0 COUNT
register we need to divide that register by the number of
cycles per MHz. But...
DIV and DIVU are expensive on MIPS (eg 75 clocks on the
R4000). MULT and MULTU are only 12 clocks on the same CPU.
On the SB1 these appear to be 40-72 clocks for DIV/DIVU and 3
clocks for MUL/MULTU.
The strategy we use to to calculate the reciprical of cycles
per MHz, scaled by 1<<32. Then we can simply issue a MULTU
and pluck of the HI register and have the results of the
division.

A basic port to the Broadcom/SiByte SB1250 evaluation board (the

"swarm"). Other SB-cpu boards will be supported by this port in

Includes support for on-chip ethernet and serial. Many features
