Dear Scott Wood,

Is there any particular reason not to change the powerpc get_timer implementation to use the timebase (scaled down to ms)?
I think so. There are some boards where we actually measure the system clock frequency against a known reference clock. IIRC this requires the TB to be independent, or something like that. [It's a long time since that code was written.]
The existing get_timer uses the decrementer, which is not independent of the timebase.
