There is one revision prior to this r0p1(r7pc) which has a different part number and are used in v1 of SoCs which are limited to only internal test platforms in the early stages of bringup and not used in actual devices out there, so I did not add it to the list but they are affected. Plus we would need to add another MIDR_QCOM_KRYO_4XX_SILVER_V1 if we are supporting them which I thought was not worth it when devices with those CPUs are not available.
Thanks, Sai
