blspec and FIT systems usually have multiple entries/configurations, where a suitable one should be selected at runtime by comparing each against the board's barebox DT compatible. For blspec, this meant we need to unflatten the whole DT only to access a single property. For FIT, this meant we expected the configuration to carry a "compatible" property and didn't even attempt to parse it out of the fdt as fallback. Both are resolved with this series.
