The current OpenBSD support relies on a few things provided by u-boot, like LCD interface driver, which I don’t think anyone is working on yet for IMX8MP. It should be possible, but an lcdif-style driver would need to be written to activate the display converter in the pocket. I started to work on this a little while ago to bring up mainline u-boot on Pocket, but haven’t got anything working yet. I also expect audio support would be an issue. I also haven’t looked into or tested the PCIe situatation, so NVMe etc. would need some work too. Mostly this is all able to be addressed through with some hard work and 
determination - but unless someone else has been working on this (probably to boot 9Front 
) it’d be a little while yet before this is possible.
