File seabios_128kb.patch of Package qemu-2.10
From 5fff5f1e79d8bc7ef24d1f8ff42c8021215f23a6 Mon Sep 17 00:00:00 2001 From: Bruce Rogers <brogers@suse.com> Date: Thu, 19 Mar 2015 16:34:31 -0600 Subject: [PATCH] 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.
