Thank you. That helps when CONGIF_SPL_GPIO is enabled.
But in case CONFIG_SPL_GPIO is disabled...

the #endif for that #if is somewhere over here.

This gives me a compilation error (rock-pi-4, CONFIG_SPL_GPIO disabled),
because of the missing include defining rockchip_cru
(and glb_rst_st as a member of it)
> + rk3399_force_power_on_reset();
This gives a warning, because the function declaration is #ifdefed out.
So we could leave the include outside the #if defined(SPL_GPIO)
and add an inline dummy function in #else,
or we could change the if (IS_ENABLED(CONFIG_SPL_GPIO)) to
#if (IS_ENABLED(CONFIG_SPL_GPIO))
I think the first is preferred in U-Boot, but not sure if that might
somehow make SPL bigger or something. I don't think so.
