From a2931b30d287b709c09f0a4ee7c1d4c26bee69d5 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 6 Feb 2016 14:31:37 -0700 Subject: dm: video: Add a temporary work-around for old stdout var Boards with a saved environment may use 'lcd' in their stdout environment variable, expecting that this will enable output to the LCD. When the board moves to use driver model for video, this will no-longer work. Add a work-around to fix this. A warning messages is printed, and we will remove the work-around at the end of 2016.
