I am not sure if I understand correctly. If they are all required by minidump driver, then this must not be in include, but stay with minidump. Remoteproc then should not touch it. I don't understand why internals of minidump should be important for remoteproc.

Let's be specific: why MD_REGION_VALID must be available for remoteproc or any other driver after introducing qcom minidump driver? Best regards, Krzysztof
