From c5b77d01d1eb0943a8241665313577b8b51203ae Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 14 Jan 2016 18:10:39 -0700 Subject: video: Provide a left margin for the text console Allow the left margin to be set so that text does not have to be right up against the left side. On some panels this makes it hard to read.
