The devicetree specification[1] defines the generic DT properties "mac-address" and "local-mac-address", that allow to set the MAC address for a network device. This is needed because many platform network devices do not define a method for obtaining a unique MAC address, and many devices lack the non-volatile storage to hold such a number. Some platforms (for instance Allwinner) derive the MAC address from another unique SoC property, for instance some serial number. To allow those MAC address to be set by TF-A, add a function that finds the DT node of a network device (by using the "ethernet<x>" alias), then adding the "local-mac-address" property into that node, setting it to a user provided address. Platforms can use this function to generate MAC addresses in a platform specific way, and store them in the DT. DT consumers like U-Boot or the Linux kernel will automatically pick up the address from that property and program the MAC device accordingly.
