From: Quentin Schulz quentin.schulz@cherry.de
If TPL_GPIO and TPL_PINCTRL_ROCKCHIP are enabled and a sysreset-gpio is provided in the TPL Device Tree, this will trigger a system reset similar to what's currently been done in SPL whenever the RK3399 "warm" boots.
There are three reasons for moving this earlier:
- faster boot time as we don't need to reach SPL to be able to reset the system on a condition we know is already met in TPL,
- have less code to be impacted by the issue this system reset works around (that is, "unclean" SoC registers after a reboot),
- less confusion around the reason for restarting. Indeed when done from SPL, the following log can be observed:
Just one other thing here: you could as well remove the call in spl_board_init. There's just one user of this currently (the Puma board) so I don't think we need to keep backwards-compatibility in the SPL.
Cheers,
Paul

possibly hinting at an issue within the SPL when loading the fitImage from MMC2 instead of the normal course of events (a system reset).
