+ This entry should not be used in normal images. It is a special entry with
+ strange features used for testing.

+ Properties / Entry arguments
+ test-str-fdt: Test string, normally in the node
+ test-int-fdt: Test integer, normally in the node
+ test-str-arg: Test string, normally in the entry arguments
+ test-int-arg: Test integer, normally in the entry arguments
+
+ The entry has a single 'a' byte as its contents. Operation is controlled by
+ a number of properties in the node, as follows:
+
Properties:
- return_invalid_entry: Return an invalid entry from GetOffsets()
+ return-invalid-entry: Return an invalid entry from GetOffsets()
+ return-unknown-contents: Refuse to provide any contents (to cause a
+ failure)
+ bad-update-contents: Implement ProcessContents() incorrectly so as to
+ cause a failure
+ never-complete-process-fdt: Refund to process the FDT (to cause a
+ failure)
+ require-args: Require that all used args are present (generating an
+ error if not)
+ force-bad-datatype: Force a call to GetEntryArgsOrProps() with a bad
+ data type (generating an error)
