+Subject: [PATCH] arm64: dts: broadcom: bcm4908: add Ethernet MAC addr
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On most BCM4908 devices MAC address can be read from the bootloader
+binary section containing device settings. Use NVMEM to describe that.
