Regarding the SoC detection, there are multiple issues to consider here: 1. We want to unify the SoC detection so it behaves the same way for all SoCs 2. We don't want the dts files to explode with boards having multiple SoC revisions. So SoC detection and features detection for SGX and DSP etc should be done after setting the major SoC class based on compatible value 3. We don't want to do pointless string comparison over and over Regards, Tony -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
