From a3868296ceee36a0562631978d3d522c19896322 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Fri, 15 Jan 2021 22:10:13 +0100 Subject: nb/intel/ironlake: Do not call `collect_system_info` twice Move wait for TXT and early ME init out of `collect_system_info`, and then drop the first call to it. Also drop a useless register read. Tested on out-of-tree HP 630, still boots.
