From deed5fbebdb879beccbe2421f1dd3af33301c51a Mon Sep 17 00:00:00 2001 From: Werner Zeh Date: Thu, 12 Jan 2017 06:29:04 +0100 Subject: fsp_baytrail: Enable graphic init per default Baytrail SoC has a bug where in some cases the DisplayPort can hang leading to a non-working display (it just stays black). To avoid this hang, a patch was introduced in 02/2016 (1c3b1112fa - fsp_baytrail: Fix a possible hanging DisplayPort) but per default not switched on so that each mainboard can decide if it wants to use this patch or not. Recently a new case of this bug was reported by Benoit Sansoni (benoit.sansoni@kontron.com) and he requested to enable this fix per default as it costs him a lot of time to find the cause and even the already available fix in coreboot. To avoid this effort for someone else in the future we can enable this fix per default as no negative side effects are known and it is now tested at Siemens and at Kontron on different mainboards with success. As the goal is to enable this code permanently the config switch is not longer needed and is removed.
