Yeah, I don't think we can get it. On the other hand, the Ralink firmware
blobs are the smallest in the whole linux-firmware.git tree. And a developer
of rt2x00 said
"One of the things I like about the Ralink hardware is that almost everything
that really matters is handled in software. Only the things that are very
timing-specific are handled in the hardware/firmware. I am not encouraging
reverse engineering, and I see no point in doing this for the Ralink
firmware, since the most interesting features for the hardware can simply be
implemented in the driver software itself." [0]
So this might be easier to reverse engineer than other blobs. Of course,
reverse engineering is not easy, but it might be possible.
