I don't think this is technically true. I think the boot rom sets the
divider for timer0 so that it runs at ~12MHz.
I think the current change to only configure timer1 and timer2 is ok
but maybe the commit message should say that timer0 is configured to
be backwards compatible at boot.
Cheers,
Daniel
