Driver support for QCA6174 chip using SDIO interface

[Erik Stromdahl]

Firmware and board files are normally distributed by the module vendor
(MuRata, Silex, etc.).

Firmware is depending on chipset, so this is something QCA should be able
to provide.

Board files are module dependent and contains calibration etc. and should
definitely be obtained from the module vendor.

If you have a discrete design you would most likely have to create your own
board file (using ART etc.)

Kalle:
Perhaps you (or someone else at QCA) can initiate the work to make the sdio
firmware publicly available?

I have obtained QCA9377 sdio firmware from Silex, but I had to sign a
License Agreement in order to obtain those files. They are not publicly
available (so I can't redistribute them just like that).
