I think we should find some way to go on here. ath79 is quite a big target, and even after having it switched to 5.4 one should give it some time for tests and possible other necessary fixes before thinking about branching a release. So far, I see three possible options:

1. Just use Hauke's hack
2. Use a different GCC version for the target, since problems are limited to 8.4.0
3. Find out the real reason for the problem

Am I getting this right? Any opinions or additional ideas?

Best
