These patches are needed in order to support rpmsg on DSP when a
resource table is available.
Changes since v1:
- add missing bracket in dtsi (patch 2/2)
Iuliana Prodan (2):
remoteproc: imx_dsp_rproc: add mandatory find_loaded_rsc_table op
arm64: dts: imx8mp: add reserve-memory nodes for DSP

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.
