+Subject: [PATCH 5/6] b44: add phylib support
+
+Most of the older home routers based on the Broadcom BCM47XX SoC series
+are using a MAC that is supported by b44. On most of these routers not
+the internal PHY of this MAC core is used, but a switch sometimes on an
+external chip or integrated into the same SoC as the Ethernet core.
+For this switch a special PHY driver is needed which should not be
+integrated into b44 as the same switches are also used by other
+Broadcom home networking SoCs which are using different Ethernet MAC
+drivers. This was tested with the b53 switch driver which is currently
+on its way to mainline.
+
+With this patch we scan the mdio bus when the sprom or nvram says that
+the PHY address is 30, if a PHY was found at this address b44 uses it.
+
+This was tested with a BCM4704, BCM4712 and BCM5354.

+Date: Sun, 6 Oct 2013 17:58:24 +0200
+Subject: [PATCH 6/6] b44: activate PHY when MAC is off
+
+Without this patch we can not access the PHY when the MAC is switched
+off. This PHY access is needed to configure the switch, which is done
+through PHY registers.
