From 05839975bf2549d5fb3bed460745e24ffd7b832a Mon Sep 17 00:00:00 2001 From: Rudolf Marek Date: Tue, 23 Sep 2008 20:36:03 +0000 Subject: Following patch adds support for Asus M2V-E SE. Works pretty well, the only problem left is with CPU scaling setup. No VGA - may work with the Xorg drivers recently released, maybe with OpenChrome too. It wont work with the little patch which will hop in soon Signed-off-by: Rudolf Marek Acked-by: Ward Vandewege git-svn-id: svn://svn.coreboot.org/coreboot/trunk@3591 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/mainboard/asus/m2v-mx_se/acpi_tables.c | 163 +++++++++++++++++++++++++++++ 1 file changed, 163 insertions(+) create mode 100644 src/mainboard/asus/m2v-mx_se/acpi_tables.c (limited to 'src/mainboard/asus/m2v-mx_se/acpi_tables.c') diff --git a/src/mainboard/asus/m2v-mx_se/acpi_tables.c b/src/mainboard/asus/m2v-mx_se/acpi_tables.c new file mode 100644 index 0000000000..86fee0c99a --- /dev/null +++ b/src/mainboard/asus/m2v-mx_se/acpi_tables.c @@ -0,0 +1,163 @@ +/* + * This file is part of the coreboot project. + * + * Written by Stefan Reinauer . + * ACPI FADT, FACS, and DSDT table support added by + * + * Copyright (C) 2004 Stefan Reinauer + * Copyright (C) 2005 Nick Barker + * Copyright (C) 2007 Rudolf Marek + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License v2 as published by + * the Free Software Foundation. + * + * 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.
