Hi Ard, Jon
Hi Gabriele :)
In our case (HiSilicon Hip05/Hip06) we are using the Designware IP that unfortunately is non-ECAM for the RC config space.
Yea, I know, and I've pinged them already.
A possible ACPI table solution was discussed already in this thread
https://lkml.org/lkml/2016/3/14/722
where <<Name (_CID, "PNP0C02") // Motherboard reserved resource>> is used to specify an Host Controller specific resource. It looks to me that this can be an approach that can accommodate different vendors/scenarios and Bjorn seemed to be quite ok with it.
Yeah, pondering that. We'll chat with a few others about it.
It comes without saying that for future HW releases we all should make an effort to deliver fully ECAM compliant controllers.
Right. Like I said, a number of designs have been fixed already.
What's your view about this approach?
Will followup over the weekend.
Jon.
