From 133647aa8689810c3e15d31ae163e7c865aeaf92 Mon Sep 17 00:00:00 2001 From: Rudolf Marek Date: Mon, 5 Apr 2010 19:47:34 +0000 Subject: Signed-off-by: Rudolf Marek Acked-by: Stefan Reinauer Add Asrock 939a785gmh motherboard. The ACPI needs more cleanup, could be done when cleaning the Mahagony board. The SidePort mode does not work because AMD hardcoded memory type in rs780_gfx.c The UMA is enabled instead. The board boots, network and int VGA works, IDE too. git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5357 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1 --- src/mainboard/asrock/939a785gmh/acpi_tables.c | 274 ++++++++++++++++++++++++++ 1 file changed, 274 insertions(+) create mode 100644 src/mainboard/asrock/939a785gmh/acpi_tables.c (limited to 'src/mainboard/asrock/939a785gmh/acpi_tables.c') diff --git a/src/mainboard/asrock/939a785gmh/acpi_tables.c b/src/mainboard/asrock/939a785gmh/acpi_tables.c new file mode 100644 index 0000000000..08b15ea046 --- /dev/null +++ b/src/mainboard/asrock/939a785gmh/acpi_tables.c @@ -0,0 +1,274 @@ +/* + * This file is part of the coreboot project. + * + * Copyright (C) 2010 Advanced Micro Devices, Inc. + * + * 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; version 2 of the License. + * + * 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.
