Broadcom Northstar family of SoCs is most commonly used for home
routers. It's an ARM platform with Cortex-A9 CPU(s).
All known Northstar devices come with CFE bootloader which almost always
expects a TRX firmware format (with exception for D-Link). Some vendors
(like Luxul and Netgear) wrap TRX in their own containers.
This board code provides:
1. Minimal kernel with support for on-SoC blocks
It enables Linux drivers for SoC, watchdog, Ethernet, switch, USB,
PCIe, LEDs).
2. Post image script building firmware images
In uses Buildroot packages tools (lzma_alone, otrx, lxlfw) to build
bootloader-compatible images that can be flashed.

+Broadcom Northstar
+
+Intro
+=====
+
+This readme covers Northstar family of Broadcom SoCs. It includes:
+ - BCM4708 (2 x 800 MHz)
+ - BCM47081 (1 x 800 MHz)
+ - BCM4709 (2 x 1 GHz)
+ - BCM47094 (2 x 1 GHz) (AKA BCM4709C0)
+
+Northstar platform is used in some home routers by multiple vendors. There are
+over 100 market devices based on it and they can all be supported with 1 kernel.
+
+There is no point in having separated board for each model. This board code is
+meant for all supported Northstar devices.
+
+All Northstar devices come with CFE bootloader by default. It's basically closed
+source as sources are available for some old releases only. There is no U-Boot (or
+any other) drop-in replacement or second stage loader with Northstar support.
+
+CFE supports flashing firmware images over TFTP and HTTP (depending on vendor /
+device setup).
+
+How to build it
+===============
+
+ $ make broadcom_ns_defconfig
+
+ $ make
+
+How to flash over HTTP
+======================
+
+Power on device and press (and hold) CTRL+C in serial console terminal. When CFE
+gets into prompt mode it'll automatically start built-in HTTP server. Navigate
+to http://192.168.1.1/ (unless IP was changed - verify with "ifconfig") and
+upload new firmware using a web browser.

I've built broadcom_ns_defconfig successfully using buildroot's
utils/docker-run. I don't have a hardware to give a try but everything
looks good to me now except I'd like to have 2 URL pointing to 2
different products for the 2 .dts cases:
- bcm4708-smartrg-sr400ac
- bcm47094-luxul-xwr-3150-v1
This because they use 2 different outputs and can help people looking
around for support for their Northstar routers, so this can lead to have
more people using this support.
Maybe you can provide them in commit log and readme.txt too and with
that included:

Applied to master after renaming ns to northstar:
board/broadcom/northstar, configs/broadcom_northstar_defconfig.
