[Buildroot] Installation of b43 firmwares

[Buildroot] Installation of b43 firmwares

[Thomas Petazzoni]

Hello,

Here is a set of two patches that allow to easily install the b43
firmware needed to operate a number of Broadcom Wifi devices.

[Buildroot] [PATCH 1/2] b43-fwcutter: new package

[Thomas Petazzoni]

b43-fwcutter is an open-source tool (BSD-2c) that extracts the
firmwares from the Broadcom proprietary drivers. Those firmwares can
then be used by the open-source b43 and b43-legacy drivers of the
Linux kernel.

[Buildroot] [PATCH 2/2] b43-firmware: new package

[Thomas Petazzoni]

This package allows to download the Broadcom Wifi drivers, extract the
firmware from them, and install them in /lib/firmware, so that they
can be used by the open-source kernel driver b43.
