[linux][PATCH v1 1/1] dts: arm: at91: Add SAMA5D3-EDS Board
From: Jerry Ray
Date: Mon Jul 25 2022 - 12:22:53 EST
Adding device tree supporting for the SAMA5D3 Ethernet Development
System board.
https://www.microchip.com/en-us/development-tool/SAMA5D3-ETHERNET-DEVELOPMENT-SYSTEM
Modifying the Makefile to include building the file.
