Subject: [PATCH] bgmac: allow enabling on ARCH_BCM_5301X
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Home routers based on ARM SoCs like BCM4708 also have bcma bus with core
supported by bgmac.

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.
