When using bootflow to boot from a block device, where the extlinux.conf file specifies `fdtdir`, a fallback device tree is being constructed from the `soc` (`k3`) and `board` (`am62x`) environment variables, resulting in u-Boot trying to retrieve `/dtbs/6.8.1+/k3-am62x.dtb`. This file doesn't exist. The environment variables `default_device_tree` and `default_device_tree_arch` are set in the config, the `findfdt` script can be called to construct `fdtfile` from the environment variables set by these config options, however this script currently isn't being run. Calling this script results in the correct device tree being retrieved: Retrieving file: /dtbs/6.8.1+/ti/k3-am625-sk.dtb Many boards are calling this script as part of their boot command. The am62x currently isn't. Rectify this so that booting works correctly.
