This is clearly mismatched here: you mark only one uart as 'enabled, but
list three of them as aliases. Having 'serial0' point to a disabled uart
may easily break applications that expect the first one to be the
console.
Best make that
serial0 = &uart2;
and drop the other ones if only one of them is exposed on the
board. If all three are usable, you should enable them all here,
and make sure that the numbering of the aliases matches the
labels on the board or its documentation.
