From 7d9068fe0b5d87fe3fe075d5d9a5f7493f5b1eac Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Fri, 4 Nov 2016 10:07:14 -0500 Subject: soc/intel/common: log event when MRC cache is updated Log when the MRC cache is attempted to be updated with status of success or failure. Just one slot is supported currently which is deemed 'normal'. This is because there are more slots anticipated in the future.
