I finally got my hands on an EVK and gave this a try. However, I did not get that far. This is with latest downstream TF-A as I still struggle with upstream there as well. Any ideas?

I'm glad you've get a board and tested our patches. Currently we're busy on other tasks so the improvement to the patch v5 has been postponed. :~(
These error is because the power supplement settings are in the later patches. Hence the clock might not stable for the cold boot up. You can just press the key on the board and warm reset it, the clock issue should be disappear.
