That's something you should be able to detect with spi_mem_supports_op(). If the controller does not support sending 4 byte addresses, it should return -ENOTSUPP and the framework should fallback to BAR setting (if the NOR supports it). Do we really need a config option for that? _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
