Also, if I make a product based of this board, with some minor
changes, is that still the sbc?

I think the compatible should be "qcom,apq8064-db600c",
"qcom,apq8064-sbc", "qcom,apq8064"

I really hope that people don't keep using the qcom bootloader dtb
picking design if they make a new product based off qcom boards with a
slight variation. They should replace the vendor part of the compatible
anyway with their own vendor prefix, and then the bootloader would need
to be updated to look for that string or something else. I really don't
want to get in the business of updating dtbTool for all the non-qcom
designs that pop up because they keep using the qcom dtb identification
scheme. It almost doesn't scale right now and that's just qcom designs.

At that other company the various dtb's that was to be picked for a
given product was always to support the various SoC versions; so those
devices always shipped with the mtp board-id and msm-id.

As far as I've seen this is how Qualcomm's Android customers does it.


But as things progress further I do see a need for being able to also
pick the right product and at that point you're right that the vendor
must change their boot loader.
