Stephen posted a patch[0] to fix this. I've squashed that into Tomeu's
commit that you reference above and my Panda board is booting fine once
again.

Please let me know if any other issues pop up. There are new WARNs for
OMAP3+ boards introduced by a different patch from Tomeu, but this is
really because the OMAP DPLL and FAPLL code are dereferencing struct clk
pointers when they should not be and is a separate issue from the
constraints patch (with a separate email thread).

Regards,
Mike
