At the moment we have some rudimentary tests of the fdt_overlay_apply() function which don't rely on overlay generation support in dtc. This is done by avoiding any external references in the sample overlay, in particularly using the 'target-path' syntax instead of 'target' to avoid needing external references in the fragment targets. Thus this test case doesn't exercise libfdt's processing of the __fixups__ node at all. We do test that somewhat in combination with dtc's overlay support. However, in the interests of being able to quickly determine which side a bug is on, it would be nice to exercise this without requiring the dtc support. This adds testcases to do so, by making some examples with manually constructed __symbols__ and __fixups__ nodes. In addition we rename some of the test data files and add some extra check_path tests to make it a bit clearer what's going on here. Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
