Hi, please reply to mailing list too.

I left out the complete lspci you sent, but attached here is the
relevant section. It is PCI 0:1.1 and 0:1.2 that require different
configuration from what stock coreboot now does.

I think the patch I sent previously has a fair likelihood of working.
Auto-detection or a choice in menuconfig is something that can come
later.
