[PATCH 2/2] arm64: dts: marvell: add support for Methode eDPU

From: Robert Marko
Date: Mon May 09 2022 - 07:00:56 EST

Methode eDPU is an Armada 3720 powered board based on the Methode uDPU.

They feature the same CPU, RAM, and storage as well as the form factor.

However, eDPU only has one SFP slot plus a copper G.hn port.

In order to reduce duplication, split the uDPU DTS into a common one.
