rpi-wifi-firmware: new package
Add firmware (NVRAM data) for the Raspberry Pi 3 and Zero W wifi module. Notice that linux-firmware provides the main firmware (brcmfmac43430-sdio.bin), but the module also needs board specific configuration (NVRAM) data. For the rpi, this data is available in the RPI firmware-nonfree git repo. As this repo contains a lot of unrelated data (~70MB), simply download the single NVRAM file instead of cloning the entire repo. A similar approach is used by openwrt and opensuse: https://dev.openwrt.org/browser/trunk/package/firmware/brcmfmac43430-firmware/Makefile?rev=49139 https://build.opensuse.org/package/view_file/hardware/bcm43xx-firmware/bcm43xx-firmware.spec?rev=b1628448b36c85abc9215eab4785ef29 [Peter: add _FIRMWARE_LICENSE as suggested by Yann] Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
