You said with plain &uart0 the kernel uses a wrong baud rate? That's
strange. For me it works and I think it's the intended behaviour to
dermine the baud rate setup by the bootloader and use this.

I'd prefer it this way over hard coding the baud rate.

This has the downside to depend on the alias. Not sure this is
considered modern. An alternative would be:

stdout-path = "/soc/internal-regs/serial@12000:115200n8";

(maybe there even exists syntactic sugar to express this using &uart0?)

Best regards
