Why is this needed? Is that really not possible to build this board
dts as actual dtb, not dtbo (and remove this 'plugin' line)? If GS
bootloader is similar to Exynos850 bootloader, it should be possible
to only use dtb, and flash empty dtbo image. Just a thought.

Why is that earlycon is needed here? The serial should work fine (and
actually even better) without that. Might be very useful for debugging
though, but in production dts I'd remove that bit. Also, not sure why
console is needed. Isn't it enough to just have something like:
stdout-path = &serial_0;
inside of /chosen node?
Btw, why isn't serial node enabled somewhere in this dts?

Here and further: maybe replace pid-function and pin-pud hard-coded
values with corresponding named constants?

No status = "okay" here? The same question goes for wdt_cl1.
