From a585358f9bb9ac417af1b8b03d08b573ca692d6a Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Sat, 6 May 2017 12:40:15 -0700 Subject: soc/intel/skylake: Enable PARALLEL_MP_AP_WORK With change a4b11e5c90 (soc/intel/skylake: Perform CPU MP Init before FSP-S Init) to perform CPU MP init before FSP-S init, MTRR programming was moved to be performed after CPU init is done. However, in order to allow callbacks after MP init, PARALLEL_MP_AP_WORK needs to be enabled. Since this option was not selected, MTRR programming always failed in ramstage for Skylake / Kaby Lake mainboards. BUG=b:36656098 TEST=Verified 2500+ cycles of suspend resume on poppy.
