From 84fdda381224f0371e27ef3f0ad77ee1103cb05a Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Tue, 10 Apr 2018 15:18:38 +0200 Subject: nb/intel/pineview: Use parallel MP init Remove guards around CPU code on which all platforms use parallel MP init code. This removes the option to disable HT siblings. Tested on Foxconn D41S.
