XLR uses an on-chip PIC clock (running at 66MHz) for cpu 0 and count/compare clock (running at CPU freq) for the other CPUs, hope this is supported with the new code. Other than that, I should be able to merge the code into XLR specific rmi/tick.c rmi/clock.c, if it works on other MIPS platforms. JC.
