test/py: gpt: make use of infra-structure
Make various changes to the GPT test: 1) Reference the disk image using an absolute path in all cases. This allows test/py to operate correctly if it's run from a directory other than the root of the U-Boot source tree. 2) Store the disk image in the teswt/py persistent data directory. This removes the need to re-generate it every time the tests are run. 3) Execute sgdisk using u_boot_utils.run_and_log() so that its output is captured in the test log. This allows debugging any problems running it. 4) Make the disk image a test fixture. This removes the requirement to always run all GPT tests, and run them in order. The current code doesn't create the disk image if e.g. just test_gpt_uuid() is executed via the test.py -k command-line option. 5) Use @pytest.mark.buildconfigspec for all feature dependencies, rather than manually implementing some of them. 6) Make all tests depend on sandbox, since they use the sandbox-specific host command. Fixes: a2f422555fc8 ("add pytests for 'gpt guid' command in sandbox") Fixes: c5772188ede9 ("add pytests for 'gpt rename' and 'gpt swap'") Signed-off-by: Stephen Warren <swarren@nvidia.com> Tested-by: Tom Rini <trini@konsulko.com>
