Hi Nicolae, when the scatter-gather patch was introduced, the feature was enabled only on tested boards to avoid regressions on other boards. So SG is enabled on sama5d4x and sama5d2x SoCs. SG is disabled on purpose on sama5d3x. For Zynq, I think the feature is still disabled just because it has never been tested.
