If EMIF is idle for certain amount of DDR cycles, EMIF will put the DDR in self refresh mode to save power if EMIF_PWR_MGMT_CTRL register is programmed. And also before entering suspend-resume ddr needs to be put in self-refresh. Linux kernel does not program this register before entering suspend and relies on u-boot setting. So configuring it in u-boot.
