It can be confusing to figure out where the devicetree came from. It seems important enough to warrant a message during boot. Add information about the number of devices and uclasses too since it is helpful to have some idea what is going on with driver model. Report the devicetree source in bdinfo too. This looks something like this, with > marking the new line. U-Boot 2021.10-00190 (Oct 30 2021 - 09:01:29 -0600) DRAM: 128 MiB > Core: 42 devices, 11 uclasses, devicetree: passage Flash: 64 MiB Signed-off-by: Simon Glass <sjg@chromium.org>
