From 31be2c969eed74510c3546bad0dbb9a7334f5843 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Sat, 3 Dec 2016 22:08:20 -0600 Subject: soc/intel/common: remove mrc cache assumptions Update the mrc cache implementation to use region_file. Instead of relying on memory-mapped access and pointer arithmetic use the region_devices and region_file to obtain the latest data associated with the region. This removes the need for the nvm wrapper as the region_devices can be used directly. Thus, the library is more generic and can be extended to work on different boot mediums.
