We had this argument a lot of times for those numbered aliases
where everything on all soc documentation, schematics and also
user documentation for individual boards, generally references
exactly those numbers :-)

But fiiiiiine, if it comes up all the time ...

I really hope, you're okay with intermitend ordering though:

	serial0 = &uart0;
	serial2 = &uart2;
	serial5 = &uart5;

because otherwise, this would cause pure chaos everywhere.

Because as I said this serial number is used on board-schematics,
board-user-level documentation, SoC documentation, even silcscreen
on boards ... so everywhere.

Similar for all the numbered busses ofthe SoCs.
