I think we should start from the beginning with support for multiple variants of the processor. I know there will be at least i.MX8 and i.MX8M, but I suppose that I am not well informed and many variants will come, exactly as we had with i.MX6.
So we need a hierarchy: first the SOC family, then the SOC variant: MX8 and MX8M (or whatever).
But in the patches, it is not clear because ARCH = SOC = M8M.
Which variants are already known ? As far as I can see, at least Quad, QuadMax and QuadPlus.
