Hi Bjorn/Mathieu, Patches from 2/17-4/17 is just a movement of functions to separate config/file. Do you think, these can be picked independently from this series ? I can send them separately, if required. @Bjorn: I have sent 13/17-15/17 separately [1] as it is needed by some folks and independent from this series.

As minidump specific data structure and functions move under config QCOM_RPROC_MINIDUMP, so remove minidump specific data from driver/remoteproc/qcom_common.c .
