From f771de445d6538d049f36c8522b9f42e8dd9c858 Mon Sep 17 00:00:00 2001 From: Pratik Prajapati Date: Wed, 16 Aug 2017 18:22:08 -0700 Subject: intel/common/cpu: Add function to get microcode patch pointer Add mp_current_microcode() function to get the microcode patch pointer. Use this function to avoid reading the microcode patch from the boot media. init_cpus() would initialize microcode_patch global variable to point to microcode patch in boot media and this function can be used to access the pointer.
