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@d0000000 {
compatible = "arm,scmi-shmem";
reg = <0x0 0xd0000000 0x0 0x80>;
no-map;
};
};

does something like this work on the rk3528?
