This information should be handled inside the CMDQ driver, allowing CMDQ users to call CMDQ APIs as usual. Therefore, CMDQ driver needs to use the mbox API to get the mminfra_offset value of the SoC, and then add it to the DRAM address when generating instructions to ensure GCE accesses the correct DRAM address.
