One thing that makes the PB different from the Pine64 is that the battery is permanently connected and the PMIC as well as probably the ARISC never loose their state completely. I had at least once to disconnect the battery to recover from a weird state while I was testing stuff in u-boot... that being said if ayufan got my pull request in for the next release there should be now a PMIC reset function enabled that is triggered by holding the power button really long (>16s). On my test image that seems to work, at least the RTC seems to be reset after that so it must remove battery power shortly as well...
