I've finally managed to get openbsd installed on an rpi3b (need
something to run signify/pkg_sign and this is what I have). Thought I'd
write up the install method because there are no useful docs at the
moment and it's a bit fiddly. (Note that only rpi3b works - 3b+ has no
network/usb, the 32-bit ones are unsupported, 4 is unsupported).
- boot linux, set the otp bit to permanently enable booting from usb (set
"program_usb_boot_mode=1" in /boot/config.txt and reboot)
- write miniroot64.fs to an SD card (I tried 6.3 up to 6.6 and -current,
that's the only one where I get any console output)
- write whatever version miniroot to a USB stick (I have a -current one)
- ttl cable on standard pins on the pinout.xyz connector 115200
- boot it. if you just leave it to itself you get

"Synchronous Abort" handler, esr 0x02000000
instead you have to do "machine exit" (thanks aalm for the tip)
and then it boots the installer.

after it has installed, remove the SD and just leave the USB drive,
cross fingers, and hopefully it will boot automatically.
dmesg currently looks like:
