So we don't know whether SFDP would be accepted by other major SPI NOR manufactures like: Spansion, Nymonix, Micronix, Toshiba, Samsung..
Thus, it might end-up like CFI (common flash interface) where some vendors support it while others did not. So unless there are more devices on SFDP from different vendors, I would prefer defer its implementation in generic driver. with regards, pekon ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
