I'd appreciate if NXP could additionally greenlight addition of:

https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/nxp/FwImage_IW416_SD/sdiouartiw416_combo_v0.bin
https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/nxp/FwImage_IW416_SD/uartiw416_bt_v0.bin

...to the linux-firmware repo.  They're necessary for SD8978 (aka IW416),
which has been supported by mwifiex since commit bba047f15851 ("wifi:
mwifiex: Support SD8978 chipset").

Back in the day when I submitted that commit, I concurrently reached out
to NXP.  Sherry Sun kindly responded that Dinesh Phatak and Pankaj
Razdan need to confirm upstreaming into linux-firmware (both +cc).


The problem is that mwifiex firmware originating from

https://github.com/NXP/mwifiex-firmware/

is available under a simple 3-clause licence, but only contains outdated
firmware for older chips.


More recent firmware available from

https://github.com/nxp-imx/imx-firmware

seems to be distributed under different and much longer licensing terms:

https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/LICENSE.txt

So I think we need confirmation from NXP before we can add the firmware
to the linux-firmware repo.

Thanks,

Lukas
