Hi, We have Android devices that are well supported by upstream kernel and other upstreams. The biggest missing part is the WiFi firmware files of Broadcom chips, which don't work using stock binary firmware provided by linux-firmware package. We need per-board firmware files for them. The NVRAM configs are also missing. The main problem is that the license of those firmware files is unknown, the NVRAM files have copyrights and that's it. The devices in question are nearly 10 years old and are long time unsupported by vendors. Is it possible to upstream those firmware files and how it can be done?
