From: Bruce Rogers <brogers@suse.com> Date: Thu, 19 Mar 2015 16:34:31 -0600 Subject: 128kb Eliminate some duplicate string segments to reduce bios image size In some build environments, we are running up against the 128K bios size limit. This change simply takes larger string segments which are used in printf style messages and uses a single copy, now referenced with a %s specifier, resulting in the needed space savings.
