On the AM335x, we first must wait for the controller to acknowledge the reset; then we can wait for the reset to complete. I believe this quirk also applies to the OMAP4 ES, but I don't have one of those to test and we don't seem to have an obvious conditional for it anyway. This quirk may work for controllers that don't require it too, but I am nervous about doing it by default because if we miss the reset acknowledgement, then we'll just time out even though everything is really hunky-dory. Also, for all sdhc, don't bother writing 0 in sdhc_soft_reset while waiting for the reset to complete; there is no need. ok matt
