- PCI coalesce can alter PCI dev.fn assignments?
That's a serious problem. I noticed that CFL FSP can reassign them without being asked to, unpredictably (e.g. if a device fails to show up in whatever timeframe FSP assumes). Solution might be simple? A chip->enable_dev() that updates b/d/f based on DID?
Ya. I think that's likely what is required.

This function should really be in common code (and I guess called from SOC specific to supply the list) as it only seems to exist in skylake/apollolake dirs...
