From f8668e98902d0ac6589ca9652206468ab370e2f2 Mon Sep 17 00:00:00 2001 From: Jamie Ryu Date: Wed, 24 Jun 2020 14:45:13 -0700 Subject: soc/intel/tigerlake: Add CpuReplacementCheck to chip options Add CpuReplacementCheck to chip options to control UPD FSPM SkipCpuReplacementCheck from devicetree. This UPD allows platforms with soldered down SoC to skip CPU replacement check to avoid a forced MRC traning.
