From 52f5cdce17f6ef4e37984e098d186cefe3950eb4 Mon Sep 17 00:00:00 2001 From: Marshall Dawson Date: Tue, 30 Jan 2018 15:28:14 -0700 Subject: soc/amd/common: Add S3 supporting functions Add functions that the wrapper will call to get and save the S3 data. The wrapper requires two types of data saved: * Non-volatile: Information that is the minimum required for bringing the DRAM controller back online. This change uses the common mrc_cache driver to manage the storage * Volatile: May be stored in DRAM; information required to complete the system restoration process.
