[PATCH v5 27/41] test: Add ut_run_test_live_flat() to run tests twice

Simon Glass sjg at chromium.org
Mon Mar 8 01:35:03 CET 2021


Driver model tests are generally run twice, once with livetree enable and
again with it disabled. Add a function to handle this and call it from the
driver model test runner.

Make ut_run_test() private since it is not used outside test-main.c now.

(no changes since v2)

Changes in v2:
- Fix conditions so non-DM SPL tests are actually run
