2021-06-10tests: Rework mocking facilityPatrick Georgi
Using the linker's --wrap feature has the downside that it only covers references across object files: If foo.c defines a() and b(), with b calling a, --wrap=a does nothing to that call. Instead, use objcopy to mark a weak and global so it can be overridden by another implementation, but only for files originating in src/. That way mocks - implemented in tests/ - become the source of truth. TEST=Had such an issue with get_log_level() in a follow-up commit, and the mock now takes over. Also, all existing unit tests still pass.

2020-06-12tests: Add some basic warnings and fix resulting issuesJulius Werner
The current test framework builds the test code without any warnings at all, which isn't great -- we have already slipped in some cases of non-void functions not returning a defined value, for example. It would likely be overkill to try to use all the same warnings we use for normal coreboot code (e.g. some stuff like -Wmissing-prototypes makes cmocka's __wrap_xxx() mock functions unnecessarily cumbersome to work with, and other things like -Wvla may be appropriate for firmware but is probably too aggressive for some simple test code). Therefore, let's just add some of the stuff that points out the most obvious errors.

2020-05-19tests: Add <tests/test.h> wrapper header and fix --gc-sectionsJulius Werner
<cmocka.h> requires a few standard headers to be explicitly included before itself or it will throw compilation errors. Having to always include these headers in the right order in every test is cumbersome. Instead, this patch encapsulates the problem in a new <tests/test.h> header that all tests should include (instead of <cmocka.h> directly). Also fix --gc-sections in the test framework which needs to be passed for linking, not for compiling.
