3. Self-Refresh Exit

Prior to this step, the DRAM is assumed to be in the self-refresh state, and CKE has been kept low, either by retention circuitry in the PHY/IO, or, after SOC power is up and the reset is done, by the controller. This step will take DRAM out of the self-refresh mode. Software must guarantee that at least 50 us have passed since the de- assertion of AMC reset before self-refresh exit, in the resume-boot case. The frequency change to 50MHz here is initiated by PMGR. For ResumeBoot, the auto-refresh must be enabled before exiting self-refresh state.
