darn ... I didn't realize that this is not sram, but main memory :-)

in freescale/s32g3.dtsi and blaize/blaize-blzp1600.dtsi I see structures like:

        reserved-memory  {
                #address-cells = <2>;
                #size-cells = <2>;
                ranges;
                
                scmi_shmem: shm at d0000000 {
                        compatible = "arm,scmi-shmem";
                        reg = <0x0 0xd0000000 0x0 0x80>;
                        no-map;
                };
        };

does something like this work on the rk3528?
