Why wait, we should just do this to start with. Even if the msm8974-db.dts is just:
/include/ "msm8974.dtsi"
{
model = "Qualcomm MSM8974 Dragonboard";
compatible = "qcom,msm8974-db", "qcom,msm8974";
}
Plus, we can do things like "disable" additional cores or such in the board.dts and have the SoC one have all 4 cores, etc in it.
