    Subject[PATCH v2 2/6] remoteproc: qcom: Move minidump specific data to qcom_minidump.h
    Date
    Move minidump specific data types and macros to a separate internal
    header(qcom_minidump.h) so that it can be shared among different
    Qualcomm drivers.

    There is no change in functional behavior after this.
