Tinker, do not touch el-cheapo undocumented SoCs/boards, IMHO this would be completely lost time. If you'd like to hack or buy hardware, better do with board/SoC which is/are fully documented. And no, datasheets are usually not good enough nor an advice to look into Linux sources...To make it completely clear, try to get some documentation for SoC you've listed, I would bet you will fail miserably. I've tried that in the past and all your choices were no go. In fact the only friendly vendor with full SoC/board developer/reference guide was Freescale/NXP of that time. Second was NVidia with their Tegra family, but this is again no-go due to missing GPU docs anyway...
Good luck! And by the way, if you'd like to donate hardware, make that a bit meaningful by offering for example ThunderX or similar kind of machine or at least those fully documented Freescale/NXP boards which are good enough as routers/gateways. I guess such offer would be tempting even to OpenBSD devs and will not be thrown into the thrash easily. :-) And if you'd like to hack on those, post your patch(es) to tech@ -- for start I guess you may get some idea from bitrig's drahn_arm64 branch and/or from FreeBSD's source tree. Generally speaking I would guess you will need to start with in-tree LLVM and make that running for you...
