This is because when EMIF registers are lost, then the controller takes care of copying the values from the shadow registers. If the shadow registers are not updated with the right values, then this results in incorrect settings while resuming.

However, this seems to cause USB detection problems for Pandaboard, about (3/8). On further investigation, it seems that doing the UHH reset is not the cause of the original Beagleboard problem, but in the way the reset was done. This patch adds proper UHH RESET mechanism for OMAP3 and OMAP4/5 based on the UHH_REVISION register. This should fix the Beagleboard NFS problem as well as the Pandaboard USB detection problem.
