Since there is no standard for SPI-NOR commands, we _should_ add new code for new chips with new opcodes. For example, if a new chip supports the quad-read with a new command 0xef, we can submit a small patch for m25p80 to fix it. We have to do it in such way, no shortcut. thanks Huang Shijie -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
