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.
|
|
