Ok, well, at least you are using the U-Boot from our OpenBSD package.
So that's good.

What device are you using to connect to the serial port? OpenBSD does
support the crazy 1500000 connection speed, but not for all serial
ports. If you use the same hardware between Linux and OpenBSD and it
works under Linux at 1500000, we should be able to make it work under
OpenBSD as well.
