"development" and "production" build use different names for serial interfaces #6

The name of the external serial interface depends on the selected kernel:

development: ttyAMA0
production: ttyAPP4

Probably this is connected to the use of the the serial line for debugging output in the development kernel?

It is not really relevant and surely does not deserve too much effort.

Also regarding #9 it may make sense to generally only use the aurtX interfaces. From what I see and also from what's written in a comment in urwerk-*.dts, aurt4 can share pins with duart, hence it could be a solution to always use aurt4 and just make that the serial0 alias which is also used for the serial console during boot (but not during early boot, switching might be glitchy, but should work)
