I went and looked at the driver and it was more complicated than what I did so I wasn't sure if there was some more advanced functionality or something that was trying to be achieved. I admit, V1 of this hardware (in the RZ/A1) was easier than V2 (RZ/A2 & R-Car), so I had to re-write our BSP driver when it came time to support RZ/A2. Basically, when they added HyperFlash support...it 'changed' how SPI support was working. I agree with Sergei that it is always better to have a common driver for common HW across different SoCs. However, it's not clear yet why there needs to be increased complexity. There were some good suggestions from the V2 series that I think complete this driver. But I have not sent out a V3 until I can better understand this 'competing' solution. Chris
