[PATCH v2 00/11] dm: test: Add unit tests for SPL

[Simon Glass]

U-Boot has about 700 tests but only a handful of these target SPL. This
is partly because SPL has limited functionality and does not have a
command interface to initiate tests.

The current SPL tests are targeted at sandbox_spl and are initiated from
pytest.

With SPL tests written in C, we can check the behaviour of of-platdata
more easily, since the test can check things directly rather than printing
out information for pytest to check.

This series adds support for SPL tests written in C, targeted at the
sandbox_spl build.

It includes quite a bit of minor refactoring to get everything working.

Changes in v2:
- Drop debug print()
- Restart U-Boot after each SPL test
- Separate out this patch from the next series and include it here
