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
