[PATCH v2 0/2] remoteproc: imx_dsp_rproc: Add coredump and recovery support

[Shengjiu Wang]

When recovery is triggered, rproc_stop() is called first then
rproc_start(), but there is no rproc_unprepare_device() and
rproc_prepare_device() in the flow. As the software reset is needed
before DSP starts, so move software reset from imx_dsp_runtime_resume()
to .load() to make the recovery work. And make sure memory is cleared
before loading firmware.

Add call rproc_coredump_set_elf_info() to initialize the elf info for
coredump, otherwise coredump will report error "ELF class is not set".

changes in v2:
- move .reset() from runtime resume to .load()
- IRAM and DRAM still in the coredump scope.
