From 5692ccfacae05175ffa5a8e9c12ef7bda3631433 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 2 Mar 2015 12:40:50 -0700 Subject: x86: video: Allow keyboard presence to be controlled by device tree At present a VGA console assumes a keyboard unless a CONFIG option is set. This difference can be dealt with by a device tree option, allowing boards that are otherwise the same to use the same configuration.
