Drop entire bootargs. Look how other SoCs do it, if you need port speed.

Never tested.
It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/

Completely wrong order of properties. Please follow DTS coding style.

You should not need the mem= and earlycon= arguments, as that data
is already part of the stdout-path property and the memory node.

The aliases are board specific, please only list the ones
that are actually enabled and wired on on a particular
board, and make the aliases match the labels on the board
rather than the internal components of hte chip.

Is that the actual address? It looks like some placeholder
that should not have been here.
