From 3dcbe628d66b648e954bc8147d4faff2983206d9 Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Thu, 23 Apr 2009 12:35:22 +0200 Subject: [PATCH] video: fix bug in cfb_console.c code Fix bug in drawing long version/info strings: U-Boot version string like "U-Boot 2009.03-05647-g7c51e06 (Apr 23 2009 - 12:40:00) MPC83XX" is long and doesn't wrap around correctly while drawing beside the logo. Such long strings partially overwrite the logo. This patch is an attempt to fix it.
