[coreboot] coreboot-2 on a DFI NF570 motherboard

[Chris Lingard]

Motherboards DFI NF-570 range, (NF570SLI-M2/G, NF570-M2/G and NF550-M2/G).

This is a suggestion to port coreboot to the NF570 series. I have 
already posted a patch, but this just duplicates the entire M57SLI stuff 
just for a two line change.  If the build script could set a flag, shown 
in the example as dfi_nf570, then coreboot would work on the above 
motherboards.

After discussion on IRC this would be a better implementation

From mptable.c

PCI_INT(0,sbdn+6,1, 23); /* HD Audio */
         PCI_INT(0,sbdn+5,0, 20); /* SATA */
         PCI_INT(0,sbdn+5,2, 22); /* SATA */
         PCI_INT(0,sbdn+5,1, 23); /* SATA */

#ifdef   dfi_nf570

PCI_INT(0,sbdn+5,2, 22); /* SATA */

PCI_INT(0,sbdn+8,0, 21); /* GBit Ether */

#else

PCI_INT(0,sbdn+5,2, 21); /* SATA */

PCI_INT(0,sbdn+8,0, 22); /* GBit Ether */

#endif

/* The PCIe slots, each on its own bus */

Tested on a DSI NF570-M2/G motherboard

The use of this motherboard eases the learning path into coreboot, 
because it has a socketed BIOS, and needs no modification.  I had never 
hot plugged a chip nor flashed a BIOS until this week
