To be clear: this applies to all RPIs?
(In particular, both RPI3 and RPI4?)

What is this the other firmware package
where OpenBSD gets the RPI dtbs?

Is this specific to the Raspberry, or is that true in general?
The content of the dtb package is a bunch of DTBs unde /usr/local/share
- I am still not sure whether there is anything else to be done
with them besides copying them over to the msdos partition
(as created at install time).
