Subject: [PATCH] remoteproc: imx_dsp_rproc: Add mandatory
find_loaded_rsc_table op
Add the .find_loaded_rsc_table operation for i.MX DSP.
We need it for inter-process communication between DSP
and main core.
This callback is used to find the resource table (defined
in remote processor linker script) where the address of the
vrings along with the other allocated resources (carveouts etc)
are stored.
If this is not found, the vrings are not allocated and
the IPC between cores will not work.
