stand/fdt: Fallback to `name` + ".dtbo" if we fail to load `name`

Authored by kevans on Jan 18 2018, 4:08 PM.



This behavior also matches a Linux-ism by allowing fdt_overlays to specify names of overlays without an extension (e.g. fdt-overlays="sunxi-h3-h5-emac")

If we fail to load the file given by a name in fdt_overlays, try again with ".dtbo" appended to it. This still allows overlays to lack .dtbo extension if user prefers it and just adds a fallback cushion.

Future work could might this from a hard-coded ".dtbo" to loader.conf(5) configuration option.
