Merge tag 'rproc-v4.20' of git://github.com/andersson/remoteproc

Pull remoteproc updates from Bjorn Andersson:
 "This contains a series of patches that reworks the memory carveout
  handling in remoteproc, in order to allow this to be reused for
  statically allocated memory regions to be used for e.g. firmware.

  It adds support for audio DSP (both TZ-assisted and non-TZ assisted)
  and compute DSP on Qualcomm SDM845, TZ-assisted audio DSP, compute DSP
  and WiFi processor on Qualcomm QCS404 and through some renaming of the
  drivers cleans up the naming situation.

  Finally support for custom coreudmp segment handlers is added and is
  used in the Qualcomm modem remoteproc driver to gather memory dumps of
  the firmware"
