The Arm N1SDP SoC suffers from some PCIe integration issues, most
prominently config space accesses to not existing BDFs being answered
with a bus abort, resulting in an SError.
"Do as I say, not as I do"?
In my former role I asked nicely that these patches not be posted
upstream, but I see that they ended up being posted anyway. Hacking up
upstream Linux to cover for the fact that a (reference) platform is
non-standard is not only not good form but it actively harms the community.
You'll have people consume this platform and not realize that it's
broken, IP won't get fixed, and generally it'll be a mess. Yes, it's
unfortunate, but so was taping out that platform without working PCI. We
all know what should have happened, and what the right move ahead is.
