From 7d95f2a329c964b54cf505503a61e8fd4f12e2a3 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 27 Feb 2014 13:26:19 -0700 Subject: sandbox: Add LCD driver Add a simple LCD driver which uses SDL to display the image. We update the image regularly, while still providing for reasonable performance. Adjust the common lcd code to support sandbox. For command-line runs we do not want the LCD to be displayed, so add a --show_lcd option to enable it.
