This patch depends on iram node and 'rockchip,force-iram' property.
the example on rk3399 to active this feature is as follows:
iram: sram@ff8d0000 {
compatible = "mmio-sram";
reg = <0x0 0xff8d0000 0x0 0x20000>; /* 128k */
};
&dmac_bus {
iram = <&iram>;
rockchip,force-iram;
};
if the 'rockchip,force-iram' not defined, fallthrough to normal usage.
