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. Because there's currently only one user of sysreset-gpio logic, and TPL is enabled on that board, so let's migrate the logic and that board to do it in TPL. 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: """ U-Boot TPL 2025.01-rc1-00165-gd79216ca9878-dirty (Nov 05 2024 - 15:31:45) Channel 0: DDR3, 666MHz BW=32 Col=10 Bk=8 CS0 Row=16 CS=1 Die BW=16 Size=2048MB Channel 1: DDR3, 666MHz BW=32 Col=10 Bk=8 CS0 Row=16 CS=1 Die BW=16 Size=2048MB 256B stride Trying to boot from BOOTROM Returning to boot ROM...
