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.
