We have pci revid macros now. Do you have plans to roll similar ones out
for bxt?
Yes. It may be that for BXT we also need to look at the PCI_REVISION_ID
field besides PCI_CLASS_REVISION, I still have to figure out the exact
mapping. (And also understand the meaning/difference between SOC vs. GT
revision IDs).
I've posted a patch with the Broxton revision ID's from the specs.
