In such a case we have to use secure aliases of some non-secure

This behaviour is controlled via a flag in smmu->bugs. It is set
based on DT information when probing an SMMU device.

:(

I guess my main comment is just some understanding on how things are wired.
It's *just* the configuration access that is secure, right? Device
transactions are non-secure, so the existing TLB invalidation code will work
correctly?
