Picking up Sarangdhar's original patches for adding core dump support to
remoteproc.

Based on the recently proposed "load resources" hook this registers segments of
the Qualcomm MDT file as dump segments which are used to build an ELF file
representing the various memory segments in the case of a crash of the remote
processor.

Bjorn Andersson (2):
  remoteproc: Rename "load_rsc_table" to "parse_fw"
  soc: qcom: mdt-loader: Return relocation base

Sarangdhar Joshi (2):
  remoteproc: Add remote processor coredump support
  remoteproc: qcom: Register segments for core dump
