I think anything that relies on bootloaders (or DT for that matter) is a bit of a non-starter for my personal use cases. Even where we're using DT relying on a sane bootloader seems a bit scary - my personal use cases would rely on updating this stuff in the field for non-technical users who would have trouble recovering from issues. > An intermediate solution that I really like is the ability to > stuff device tree fragments on extension board themselves, but that > can only work for new designs and causes problems when that information > is not actually correct. I can see the theory, but I can also see some practical concerns. And with the boards I'm working with we currently have 8 bits of data so... -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
