Today and yesterday's -next is failing to boot on rk3399-firefly in two configs:

which is rather entertaining.
Based on the logs from successful boots, I see it's CPUFreq that gets probed after fan53555-reg. I also see that it warns about unlisted OPPs in the successful boots. I guess, the undefined instruction could occur if there's issue with CPU DVFS(under voltage or frequency that's not supported). I don't have much knowledge on the platform, I am just guessing on the possible cause here.
