From 87c7ec7c0677ec5fda4a9cebb95c06edb23a96ba Mon Sep 17 00:00:00 2001 From: Shreesh Chhabbi Date: Thu, 3 Dec 2020 14:07:15 -0800 Subject: soc/intel: Remove INTEL_CAR_NEM_ENHANCED_V2 config option SF Mask MSRs' Programming which was done under this config selection will be moved under a new config option called CAR_HAS_SF_MASKS. This segregates the eNEM programming sequence based on sub features supported in each processor. Bug=b:171601324 BRANCH=volteer Test=Build volteer build and boot on Delbin EVT.
