+Subject: [PATCH] bgmac: register fixed PHY for ARM BCM470X / BCM5301X chipsets
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On ARM SoCs with bgmac Ethernet hardware we don't have any normal PHY.
+There is always a switch attached but it's not even controlled over MDIO
+like in case of MIPS devices.
+We need a fixed PHY to be able to send/receive packets from the switch.
