At present U-Boot has two broad sets of tests in the C code: driver model tests which do a lot of pre-/post-init and command tests which do not.
This separation makes it slightly harder to write a test, since there are two different test-state structures and different rules for running the two different test types. At present these rules are determined by where the test is (actually its prefix).
All unit tests can be run from the command line with the 'ut' command. Since SPL does not have commands, it currently calls the test runner directly and offers no control of which tests are run.
This seems like a good time to refactor the tests into a unified test runner, allowing U-Boot proper and SPL to use the same path, perhaps with some different conditions along the way.
This series sets up a unified runner called ut_run_list(), which runs a set of tests from a linker_list. Driver model tests are distinguished by a new UT_TESTF_DM flag so that the necessary init and cleanup can still be done.
The runner is modified to support running SPL tests that are not solely for driver model. An example test for FIT loading is added as a demonstration.
In addition, some documentation is added to explain how to write tests.
For the series, applied to u-boot/next, thanks!
