looks good, why is it a draft ?
CI test for xilinx passed

just want to test on real hw that it works and then ill remove "draft"

this patch fixes the build
i quickly try to test on zedboard but the spi read at init was not returning for some reason that needs to be debugged further. (i build the HDL with make INTF=1)

Ok, given that XPAR_AXI_AD7616_BASEADDR and the SPI issue could be related I'm not going to merge for now, until you have a fix. If we're 100% sure XPAR_AXI_AD7616_BASEADDR is correct then I could merge it and treat these as separate issues, this one fixes the build (and I'd merge it), the other fix will address the SPI init issue. Let me know.

@buha im sure XPAR_AXI_AD7616_BASEADDR is correct. i think you can merge this.
i need to find some time to look at the HW setup (there is a resistor to change serial/parallel modes)
and probe the spi lines to see what is going on with this project... it might have been my setup
