Ok, I'm not sure how that's going to work though. If all these 'SBC' devices are using the same bootloader and that bootloader is looking into SMEM for the different device identifying attributes (called socinfo in the downstream kernel) we're going to need to make sure that the devices identify uniquely. There is the 'subtype' attribute, which is just a number to identify different variations of a similar board. I hope that all the 'SBC' boards are using different subtypes or things are going to start getting messy. -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project -- 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
