From 68f3fc767c33694d63f1dbaef5ff1b0a4cb27d43 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 2 Jul 2020 21:12:24 -0600 Subject: [PATCH] video: Update normal console to support copy buffer Update the implementation to keep a track of what it changes in the frame buffer and then tell the copy buffer about it. Use the special vidconsole_memmove() helper so that memmove() operations are also reflected in the copy buffer.
