Is there some reason why we can't do this in the OMAP4 PM code? At some point, I think it would be good to essentially disable all PM at boot, and then let the PM code specifically enable autoidle later in the boot process, etc. The idea being that !CONFIG_PM would result in a chip programmed for lowest latency, etc.
