I agree about it I just mean that if you have the same board with 2 SoC which
are pin to pin compatible detect the soc type will be usefull as the soc
resource may not be the same

In that scenario, you would put all SOC specific data into one .dtsi
file and all board data into another .dtsi file and then create a
description for the combination using a trivial .dts file with two
include statements. This is all solved outside of the kernel already,
so there is no need for infrastructure in the kernel.

except in this case you must have 2 machine id which can be avoided if you can
detect the soc at kernel level
