OpenBSD 7.1 on PINE64 RockPro64

This is a small write-up about installing OpenBSD 7.1 on a PINE64 RockPro64 SBC.

RockPro64 is a beefy single-board computer made by a company that brought us awesome devices like Pinebook Pro (laptop), Pinecil (soldering iron), PineTime (smartwatch) and of course PinePhone. The board utilizes the same hexa-core processor as Pinebook Pro - Rockchip RK3399, and 4 gigabytes of LPDDR4 RAM.

One of the distinct features of that computer is a PCI-express X4 socket. Unfortunately I wasn't able to use any video card there even with stock" GNU/Linux - ARM64 GPU drivers for AMD/NVIDIA is just not there yet I assume. The slot is often being used for a network cards and SATA controllers - there is even an official case for RP64 with 3.5'' hard drives spots inside, quite handy for a homemade NAS or something of sorts.

Exactly what it says on the tin.
