+Subject: [PATCH 1/3] ARM: BCM5301X: initial support for the BCM5301X/BCM470X
+ SoCs with ARM CPU
+
+This patch adds support for the BCM5301X/BCM470X SoCs with an ARM CPUs.
+Currently just booting to a shell is working and nothing else, no
+Ethernet, wifi, flash, ...
+I have some pending patches to make Ethernet work for this device.
+Mostly device tree support for bcma is missing.
+
+This SoC is used in small office and home router with Broadcom SoCs
+it's internal name is Northstar. This code should support the BCM4707,
+BCM4708, BCM4709, BCM53010, BCM53011 and BCM53012 SoC. It uses one or
+two ARM Cortex A9 Cores, some highlights are 2 PCIe 2.0 controllers,
+4 Gigabit Ethernet MACs and a USB 3.0 host controller.
+
+This SoC uses a dual core CPU, but this is currently not implemented.
+More information about this SoC can be found here:
