Sorry for the delay in getting this review back to you.

One thing you might want to consider. I note that in the latest upstream
submission this has changed from libio to some other name. Adopting what
will (presumably) be the name used upstream might make it less
cumbersome when you need to backport future changes.

At this point though this looks safe enough to merge.

- Minimal impact to non-arm64 architectures
- New drivers will only be used on relevant platforms, so no impact on
  other arm64 platforms from those drivers
- Impact to other arm64 platforms is kept as minimal as possible
- Smoke testing against other architectures and platforms
