' first' open-source ARMv9 motherboard surfaces – Radxa Orion O6

Some of their other boards have PDF printouts of the Cadence OrCAD schematics, and even DXFs of the top and bottom layers of the board, but none have actual hardware source documents.
Their Github repositories contain little more than pre-built images for the boards.
Older boards do have CPU block diagrams and pinouts of the IO ports (which should be standardized, but it's nice to have them in one place) but there are no real datasheets for any of these CPUs.
Yes, they claim "Everything about Radxa SBCs is open" but I don't see it.
Ah, now I see how you'd customize one of these open-source products: Their "Services" page offers "Personalized PCB logo and customer SKU, and changes to pin-compatible materials, such as Wi-Fi speed or expanded operating temperature range" with no non-recurring engineering costs if your order is more than 500 pieces or $50,000" or you can call them for custom base-plate design or other mechanical changes to the layout.
But the marketing bar graphs and lack of efficiency data, along with not (yet) seeing any of the board firmware (says it uses EDKII) makes me a little worried.
I've been burned buying new Radxa hardware in the past, without ever seeing software support materialize later (or half-implemented features that only work on one or two barely-maintained distros...).
But I would love to have another option for an efficient Arm board. Hopefully the efficiency is also close to M1 which is pretty amazing.
Then I read your username. Big fan :)

Really looking forward to your review of this.
Probably the board schematic… what a joke
If we want truly open-source hardware we'll have to go back to relay computers. Everything beyond that is "a joke".
It’s a flawed surrogate of course - lower performance and higher cost than an asic produced at volume - but the open source hardware aspect is very strong.
Actually, it's not open unless you can make it from hydrogen atoms.
however awesome an open source fabbed asic or fpga would be of course.
There are degrees to things. It's not cool to try to claim the prestige of "open source" when the entire board is nothing but a vehicle for your very-much-closed processor design.
You can get the board design and order it manufactured yourself, or you can change it to suit a different processor that's more open.
I'm really glad to see ARM finally after decades have something semi competitive versus buying an x86 mini-pc.
One question, hoping the x16 slot has bifurcation support. But this seems like such a perfect board for a SSD NAS. If the slot can be divided into x4 or ideally down to x2 lanes. I'm not sure what bifurcation support entails, what it requires: anyone know?
