You might mention here that (following our initial stub) this commit is
now apparently based on the CodeAurora BSP branch foo (and therefore
adding its last-year copyright below and separate from 4/8).

@NXP: Should this be updated to include 2021 from your latest BSP
releases? Do you want it visually aligned by adding the ASCII-art?

Note: In the past there had been controversies as to whether to define
aliases globally for a SoC or in a .dts specific to a board's usage.
In this case it does not seem to matter much, as uart0 is being used as
console on the reference boards.

Yes for both questions. The copyright year sould be updated to 2021 and
should be visually aligned.
