The tick.c code currently uses the CPU clock frequency (if known) for
calibrating DELAY() and the MIPS on chip ticker, implemented using the
cycle count register, a bit like TSC on x86.
It appears that the YAMON monitor includes a function to discover the
clock frequency from the platform firmware.(I don't see a way to do this
for CFE firmware).
GXemul's yamon shim does not support this function, a patch should be
quite trivial to implement.
