Hi Marek,

Thank you for the patch.

I've tested this with

$ ./test/py/test.py --bd sandbox --build -k ut

Followed by:

$ ./test/py/test.py --bd sandbox --build -k cmd_zip

And I see:

FAILED test/py/tests/test_ut.py::test_ut[ut_dm_dm_test_cmd_zip_gzwrite] - ValueError: U-Boot exited with signal 11 (SIGSEGV)
FAILED test/py/tests/test_ut.py::test_ut[ut_dm_dm_test_cmd_zip_unzip] - ValueError: U-Boot exited with signal 11 (SIGSEGV)

The full logs are available here:

(note that the version is reported as dirty because I added a small to
diff to fix the compile issue I reported in [1])
