Of course - but I don't currently feel like bending over backwards for
this one chip. Keep the working stuff working.

I can gladly say that using Ghidra on the firmware, v4, v5, and v6 is
amazing. Export symbols help a lot, and it gives you a good idea of what
is going on; with the exception of the decompiler giving goto statements
that jump all over the place and make things confusing :/

But again, it's legacy.

As for newer gens - I thought they are already provided by Broadcom
devs in the kernel? I may be wrong, I can look later.

Thanks :)
