This is a BCMBCA SoC, a variant of BCM6856.

I am working on BCMBCA support (ethernet etc) for the
related BCM6846, but the work is upstream-first oriented,
i.e. I want to land major changes in the Linux kernel before
I add OpenWrt support.

Development branch for OpenWrt:
https://github.com/linusw/openwrt/tree/pr-bcmbca-xg6846b

It will take the time it takes.
