Rev ES

There is now a
PandaBoard-ES which
includes an OMAP 4460 at up to 1.2GHz. Several important differences
make it important (at the present time) that the MLO/u-boot/kernel be
specifically crafted for the 4460. The thermal management is not in the
mainline 4430 code as yet and could cause unwanted thermal problems. So
BEWARE of running any code built for the non -ES PandaBoard on the -ES
model.
