From fb49b6f65a699b3463f5b2f16815340bbd3dabeb Mon Sep 17 00:00:00 2001 From: Iuliana Prodan Date: Fri, 13 Oct 2023 18:27:30 +0300 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.
