Atheros firmware support

Atheros firmware support

[Ludovic Courtès]

Commit 1306b0b fixes a miscompilation of the ath9k-htc-firmware package
(I had overlooked the fact that the upstream source patches Binutils and
GCC to get things done.)

Then commit f34c56b allows Linux-libre to load firmware that is listed
in the ‘firmware’ field of an OS declaration.

With all that, I’m happy to say that I can use the RYF-certified WiFi
device by ThinkPenguin¹!  :-)

This is a bit frightening:
$ git diff 1306b0b003a557105d3b27e44052db217c7283d3^ 1306b0b003a557105d3b27e44052db217c7283d3 | wc -l
29177

But congratulations!

Yeah.  The patches come from the firmware’s source code repo:

  https://github.com/qca/open-ath9k-htc-firmware/tree/master/local/patches

Normally, one would run ‘make toolchain’ in the firmware’s source tree,
which would build a patched tool chain.  But here, we build the tool
chain ourselves, so we need to import these patches.

We can only hope that Qualcomm will get those patches upstream.
