"Reference Design Board 2"?

@NXP: Note that since there's no distinction between S32V and S32G on
the Kconfig level, we decided not to add a white line here. If you wish
to visually separate them, that could be changed.

For reference:

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/arch/arm64/Kconfig.platforms

speaks about S32 (without V), so did not need to get updated for S32G2.

Is there any marking on the PCB that a /* ... */ comment could reference
here? Right now uart0 is close to stdout-path above, but that will
change once more device nodes get added and enabled alphabetically.

No clock-frequency or clocks property needed?

"Board" missing.

What is uart1? Please add a comment. Does it actually work without
clocks property?

Thanks,
