We try to keep our device-trees in sync with Linux. The device-tree available under $fdtcontroladdr should be usable to boot the OS. We should avoid anything that could lead now or in the future to a conflict with the the OS usage of the device tree nodes. Please, use in the example a compatibility string that is unique to U-Boot. How about: "uboot,sandbox-sysinfo"? Best regards Heinrich

We use "sandbox" as the vendor throughout U-Boot so I don't feel we should change now. Perhaps as part of an effort to send our bindings upstream? Regards, Simon

Add a simple binding file for this, so that it is clear what this binding directory is for.
