From 89e671e3f3d5754e78efc447f13386ced719f1f7 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Wed, 1 Jul 2009 22:08:21 +0200 Subject: Replace signrom with shell script v3 In order to not execute code we just compiled, let's replace signrom with a shell script that does the same thing while staying compatible to pretty much every system available. This should make cross-compilation for windows easier. aliguori: fix build when objdir != srcdir Signed-off-by: Alexander Graf Signed-off-by: Anthony Liguori --- pc-bios/optionrom/signrom.sh | 45 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 45 insertions(+) create mode 100755 pc-bios/optionrom/signrom.sh (limited to 'pc-bios/optionrom/signrom.sh') diff --git a/pc-bios/optionrom/signrom.sh b/pc-bios/optionrom/signrom.sh new file mode 100755 index 0000000000..4273d1f0e0 --- /dev/null +++ b/pc-bios/optionrom/signrom.sh @@ -0,0 +1,45 @@ +#!/bin/sh + +# Option ROM Signing utility +# +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
