VPU on imx6 solo

The iram size on reserved for vpu on imx6 solo seems to be zero, the vpu node in  device tree file passes zero as iram size where as imx6qd it is 0x2100.

arch/arm/boot/dts/imx6dl.dtsi

 

vpu@02040000 {

                iramsize = <0>;

                status = "okay";

            };

 

Our custom video driver uses VPU APIs for h264 encoding and during initialization it gives a warning message as

" VPU iram is less than needed, some parts don't use iram"

 

The internal ram in imx solo is 128 KB. Why iram memory is not been used for vpu on imx6 solo ?
