+Subject: [PATCH 09/16] rpi: Add identifier for the new RPi400
+
+The Raspberry Pi Foundation released the new RPi400 which we want to
+detect, so we can enable Ethernet on it and know the correct device tree
+file name.
+
+So far the Raspberry Pi foundation is using the RPi4b device-tree file
+to boot RPi400. I see no reason not to do the same as they are
+completely compatible.
