From 478a1212ef0725fe86c59527f5aa30be5606c329 Mon Sep 17 00:00:00 2001 From: Tristan Corrick Date: Wed, 24 Apr 2019 01:24:30 +1200 Subject: mb/supermicro/x10slm-f: Do SIO setup in bootblock Lynx Point switched to doing mainboard-specific super I/O setup in the bootblock with commit d893a2635fdd ("sb/intel/lynxpoint: Enable LPC/SIO setup in bootblock"). The X10SLM+-F was added while that commit was in review, and hence did not receive the necessary changes to SIO setup. This patch has not been tested on hardware.
