We already have a representation of the device tree loaded, in fw->fdt.
You can use the standard libfdt accessors on this data.

Then, the compile time check becomes FWTS_HAS_DEVICETREE (to determine
whether you can use the libfdt functions), and you'd skip the test if
you have no fdt data:

	if (!fw->fdt)
		return FWTS_SKIPPED;

Cheers,


Jeremy
