[OpenWrt-Devel] [PATCH 0/4] Add Raspberry Pi 3 support

[Hauke Mehrtens]

Hi Arend,

could you or someone else from Broadcom pleases add the firmware for the
BCM43430 SDIO to linux-firmware. This module is used in the Raspberry Pi
3 and it would be a lot easer for distributions to have the firmware in
linux-firmware.
