So this change will have the effect of changing the console on
ipq5018-rdp432 from gpio31-gpio34 to gpio28, gpio29.
Have you verified that change on hardware or the schematic ?

This has the wrong UART pinout ?
Is this change something that should be expressed for a particular board ?
Infact again checked it, the correct pins are "gpio20", "gpio21".
It works so far because u-boot has configured it.
