commit 08b14667047688b52aab01c686c42ea9ac458815 Author: Kyösti Mälkki kyosti.malkki@gmail.com Date: Mon Oct 17 18:08:13 2011 +0300
Add support for A-Open DXPL Plus-U motherboard
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
