I spoke a little too soon.

While testing these patches I noticed that the koelsch patch
cases there to be no kernel output to the console (during boot)
when booting using legacy C.

I assume that this is due to removing
console=ttySC6,115200 from bootargs.

I also assume this affects all boards that can still
be booted using legacy C.

I have dropped this series for now.
