I heard about OpenBSD/Loongson still doesn't support newer Loongson 3A/3B system, then got contact with some Lemote staff and they tell me there are some Loongson 3A1000 and 3B1500 machine in are ready to donate. These board was used as Debian auto-build server and can ship from Germany.
Also, newer Loongson 3A2000/3A3000 hardware are available by ship directly from Lemote's China office, but the parcel service may not at time since the COVID-19 pandemic. Please reply this post if you have interest to port OpenBSD on newer Loongson hardware.
