There are different parts from one SoC. Take i.MX6ULL for example, some part might not have ENET, some might have; some might not have USB, some might have. The information could be got from OCOTP, to make one image support the different parts, we need runtime disable linux kernel dts node and uboot driver probe if the corresponding module not exists in the part.
