flashrom

We just had an in-depth discussion on the topic of #ifdef vs weak symbols in unit tests and decided to keep #ifdef for now.

Reasons (from meeting notes):

1. Weak symbols makes code less obvious: harder to understand what is going on
2. Flashrom (non-test code) does not use weak symbols, maybe tests should not either? We should use the same concept in flashrom and test code. We can switch both to weak symbols, or none.
3. Let’s think about it later?
4. Not blocking release.
5. Ideally we won’t be touching ifdefs until we drop make

Closing this ticket, but we may return back to the question of weak symbols after the release.
