qca6164 support

[Enrico Tagliavini]

Hi Victor,

I think you should have called your firmwware firmware-4.bin and not
-5.bin. In fact in the top of the file I have it says ">
firmware-4.bin". File names matters as far as I understood. Feel free
to check archives of this list I saw somebody talking about this
argument not long ago.

Good luck.
Enrico
