"""A fake entry used for testing
|
|
|
|
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-unknown-contents: Refuse to provide any contents (to cause a
|
|
failure)
|
|
bad-update-contents: Return a larger size in ProcessContents
|
|
bad-shrink-contents: Return a larger size in ProcessContents
|
|
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)
