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.
The ideal case is the firmware (U-Boot, EDK2 etc) supplies a device tree and resides on it's own storage. Then we could have single install images that work everywhere without having to distribute board specific U-Boot and dtb files.
As most arm systems aren't ideal there are ports/packages that build device trees from the linux source and package up those provided as part of raspberrypi-firmware.

Then there are some U-Boot targets with builtin device trees.

The parts of the tree that build install images with U-Boot/dtbs:

Anyhow, I???m fine with that change.
