From 0d89efef773318b241df7cb1295ac72742e6f848 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 17 Oct 2012 13:24:59 +0000 Subject: lcd: Add CONFIG_CONSOLE_SCROLL_LINES option to speed console When the cursor position gets to the end of the LCD console we normally scroll by one line. This adds an option to increase that value. Console scrolling is often slow, and if a large amount of output is being sent, increasing this option to 10 or so will speed things up considerably.
