So far there is no test coverage. Let's improve this as much as possible without fully understanding all use cases. This first test adds a devicetree overlay to a build configuration without signing, since signing is apparently not yet meaningful when PREFERRED_PROVIDER_virtual/dtb = “bborg-relay-00a2” is used. It is also not entirely clear how these external devicetree overlays are used by the configuration nodes of the FIT image. Currently, one configuration is created per dtb dtbo node, which is not really useful for dtbo nodes. Before this test can be extended to test devicetree overlays and signing, the code that creates the configuration nodes in its file probably needs some improvements in terms of more flexibility in defining the references from configuration nodes to image nodes.
