Re: [coreboot] v3 HT

[Carl-Daniel Hailfinger]

The explanations by Tom and Marc made a few things clear for me:
- The physical HT structure is not what we want to model.
- The appearance of HT and topology in PCI config space is what matters.
- 18.0 is not a PCI bridge, don't pretend it is one

With that in mind, I'd like to propose another dts.
I know that it has its own quirks, but it can serve as a discussion point.

I'm pretty sure someone already posted a lspci -tn and lspci -n for the
Serengeti, but I can't find it in my mails right now. A pointer to the
archives and/or a repost would be appreciated.

Regards,
Carl-Daniel
