From 655ef61937ccd65c19e8ddeb3da1dd40c8238cf7 Mon Sep 17 00:00:00 2001 From: Tristan Corrick Date: Wed, 31 Oct 2018 02:26:19 +1300 Subject: sb/intel/lynxpoint: Provide a function for mainboard super I/O config The super I/O setup needs to be done after the LPC is enabled. For Lynx Point, configuring the super I/O in `mainboard_romstage_entry()` is too early to get a serial console output. To remedy this, add a function `mainboard_config_superio()` that will be called at the appropriate time, and can be overridden by mainboard code.
