351 When no configuration is explicitly selected, default to the
352 one whose fdt's compatibility field best matches that of
353 U-Boot itself. A match is considered "best" if it matches the
354 most specific compatibility entry of U-Boot's fdt's root node.
355 The order of entries in the configuration's fdt is ignored.
