[Tutorial] Build, customize and use MediaTek open-source U-Boot and ATF

Indeed, I always use powerdown to cleanly power the board down and unplug the power. So I also will need to revert it.

shame they didn’t do like pi5 with a power down button

I wonder why real powerdown is not possible for r4 because it has a pmic (r3 does not).

But for me it is enough to simply halt and not reboot to safely switch off.
