From 91162705a65e87c56d9fc58edfe597140d1b4d53 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Thu, 3 Nov 2011 15:22:01 +0200 Subject: Add support for A-Open DXPL Plus-U motherboard MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is an old (pre-2005) entry-level server mainboard. The code is adapted from mainboard/intel/xe7501devkit. Featured chips: - Dual socket604 - E7505 northbridge - 82801DB southbridge (with EHCI debug port) - 82870p2 PCI-X bridge - LPC47M102S-MC super-io - 512kB FWH flash (flashrom does the job well) What works: - Dual-Xeon P4/HT boot with microcode update - RAM: registered ECC DDR266 in dual-channel - PCI-X slot interrupts with ACPI and I/O apic - On-board PCI-X GbE and SCSI - ACPI power-off and wakeup with PME# Notes : - Current ACPI is more or less a mess - Interrupts do not route correctly with PIRQ - MP-table is not implemented - Issues with reboots remain (cold and warm) - Many superio devices are disabled by default - Audio codec is not investigated Change-Id: I02d18c83f485a09ada65dde03bcc86e9163f2011 Signed-off-by: Kyösti Mälkki Reviewed-on: http://review.coreboot.org/303 Tested-by: build bot (Jenkins) Reviewed-by: Patrick Georgi --- src/mainboard/aopen/dxplplusu/acpi/p64h2.asl | 97 ++++++++++++++++++++++++++++ 1 file changed, 97 insertions(+) create mode 100644 src/mainboard/aopen/dxplplusu/acpi/p64h2.asl (limited to 'src/mainboard/aopen/dxplplusu/acpi/p64h2.asl') diff --git a/src/mainboard/aopen/dxplplusu/acpi/p64h2.asl b/src/mainboard/aopen/dxplplusu/acpi/p64h2.asl new file mode 100644 index 0000000000..39586997d2 --- /dev/null +++ b/src/mainboard/aopen/dxplplusu/acpi/p64h2.asl @@ -0,0 +1,97 @@ +/* + * This file is part of the coreboot project. + * + * Copyright (C) 2011 Kyösti Mälkki + * + * 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.
