We should do a new line for each board as other arm64 vendors have done?

Should be qcom,apq8096-sbc? At least I have to use that on my board to
match the board ids.

I agree, this should match up with the dtbTool. I have been manually 
patching up dtb to include the board-id, pmic id stuff.

I will fix it in next version,

Did not look at full details but, For some reason dtbTool does not 
support multiple compatible strings, do you think it makes sense to add 
this support in dtb tool to cope up with compatible strings like:

compatible = "qcom,apq8096-db820c", "qcom,apq8096-sbc";


Thanks,

Hmm I suppose we can add support to look for the first compatible
that matches something that we can generate an id for? That would
allow us to have the LK compatible and then whatever is more
specific than that which the bootloader doesn't care about.
