Good Morning,
Heads up to anyone still tracking this.
A few bugs were fixed in mainline Linux and mainline Arm Trusted Firmware to fix reboot and power-off issues with this board.
Arm Trusted Firmware was not handling reboots correctly so reboots would usually hang up.
Arm Trusted Firmware was not powering on the A72 cluster after a reboot, causing boot issues.
Mainline Linux was calling PSCI (Arm Trusted Firmware) for power-off, when PSCI cannot power off this board currently.
It has been fixed so now Mainline Linux calls the rk808 to initiate power-off.
So if you were using mainline code and had reboot issues, you need to update to the latest ATF.
