In case of firmware assert snapshot of firmware memory is essential for debugging. Add firmware coredump collection support for PCI bus. Collect RDDM and firmware paging dumps from MHI and pack them in TLV format and also pack various memory shared during QMI phase in separate TLVs. Add necessary header and share the dumps to user space using dev coredump framework. Coredump collection is disabled by default and can be enabled using menuconfig. Dump collected for a radio is 55 MB approximately.
