We are working, for the i.MX team, in a way to reduce code duplication
for BSP of similar SoCs. So the approach we are following uses:

    This allow to grouping of different settings for similar platforms.

    To use the class, specify, for example:

     MACHINEOVERRIDES_EXTENDER_soc = "group1:group2"
