To: u-boot
From: Stephen Warren <swarren@nvidia.com>
Invoke each "ut"-based unit test as a separate pytest.
Now that the DM unit test runs under test/py, remove the manual shell
script that invokes it.
Signed-off-by: Stephen Warren <swarren@nvidia.com>
Acked-by: Simon Glass <sjg@chromium.org>
Tested-by: Simon Glass <sjg@chromium.org> # v2, on sandbox

v3: Adapt to new symbol file name.
v2:
- Only run "ut"-based tests, not other C-based tests which haven't been
converted to run under "ut".
- Rely on the build process having run objdump; don't run it from the
test system.
