[LinuxBIOS] [PATCH] Very preliminary nVidia MCP55 support

[Ed Swierk]

I understand a number of folks besides me are working on porting
LinuxBIOS to mainboards based on the nVidia MCP55 chipset.

I thought I would post the work I've done so far on the DFI LANParty
UT NF590 mainboard in the hope that our efforts could merge sooner
rather than later:

Thanks mainly to Yinghai's work on Model F support, I've managed to
set up the serial port, initialize DRAM, get both cores up, and boot a
Linux payload. I haven't gotten very much of the southbridge working
yet: the NICs are recognized but interrupts aren't getting routed
property, and neither IDE nor SATA devices are recognized.

Help and feedback are always welcome.
