There's a minor bug in what I posted, however.  ti814x needs timer_init
called _before_ pll_init() as setting the sata clocks (which are shared
with other periphrals that we do enable right now) needs udelay(50) to
settle as we go along.  That also needs to be commented in the code as I
had to think about it for a bit to recall exactly what was going on.

You aren't using a different clock crystal rate than the reference
platforms, are you?  I know that's a problem that needs solving still.
