The I didn't use the generic time.c back then is power management. The
CP0 counter sleeps when using the 'wait' instruction, so in that case
you have to use a different counter with a rather poor resolution. The
modifications I had to make were such that they couldn't go in the
generic time.c. But that area definitely needs to be revisited and
