Anyway, what I meant is that such driver should not rely on CPU identification at all, especially since it does not require some specific CPU features but it tries to guess which SoC revision it is and which device (not CPU) bugs have been fixed. Better if they follow Mark R's idea to pass such information in DT for the device. So maybe the revert is not too bad an idea. -- Catalin -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
