[U-Boot] [PATCH v2 4/5] test/py: test_fs: add tests for creating/deleting many files

[Heinrich Schuchardt]

As both Tom and I wrote to you in reply of to the first version of the
patch it is not clear how these tests can be run.

make tests

simply skips them.

Could you, please, provide a description in test/py/README.md.

Best regards

Heinrich
