This assumes that the devicetree files in U-Boot and the OS are the same.
As it’s our goal to keep Linux devicetrees in sync with U-Boot this patch should
be fine in the long-term. But at the moment this only applies for rk3399-firefly (on
Linux).

Mark, where would one find the devicetrees included in OpenBSD?
I looked in sys/arch/amd64 but couldn’t find any.

Anyhow, I’m fine with that change.
