Hi guys, Zynq supports 8 and 16bit ONFI nand flashes. We can count number of connected pins and from that we know if 8bit or 16bit nand flash is used.
I have looked at the code and contains ONFI detection with correct detection of bus width + checking later. Why also not setup proper chip->options for NAND_BUSWIDTH_16? Not sure how others but if driver expect just ONFI devices and support 8 and 16bit options why not just to setup chip options based on information from ONFI or not check that (busw != (chip->options & NAND_BUSWIDTH_16)) for onfi case. Just wanted to get input from you before I will try to create patch to support this. I just want to be sure that I am not doing something what it is wrong for other platforms.
