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.

i.MX8M is different from Quad/QuadMax and etc. It is similar as i.MX6/7
, all is controlled by Cortex-A[x]. So I choose a new SoC family entry
here. Just like we have MX7 and MX7ULP. MX8 will be used for Quad, QuadMax
QuadX. MX8M here is used for i.MX8MQ and etc.

What do you think?

Thanks,
Peng.

Ok, this is also my expectation.

I have so less information and knowledge about the new NXP processors
and I cannot better help, I trust your judge. But what can we share
between M8M and M8 ? What about all stuff going into mx8m directories
(cpu, closk, ..) ? Could they be reused for MX8 or do they remain an
island ?

MX8M and MX8 has different architecture. 
To MX8, all clocks, power domains, pin configuration, and reset and etc
are all controlled by SCU and different clock/power/xx architecture with MX8M.

So most code could not be reused.
