Hi, The offset of some registers of the SMC is different between sama5d3/sama5d4 and sama5d2. An helper function has been added to retrieve the correct layout with the help of a new compatible string for sama5d2. The atmel-ebi device will store the register layout to allow the nand controller to setup correctly the data interface.
