as said the firmware here seems to work for me (after renaming):
https://github.com/nxp-imx/imx-firmware/blob/lf-6.6.3_1.0.0/nxp/FwImage_898=
7/sdiouart8987_combo_v0.bin

I can use bluetooth together with btnxpuart driver and firmware
/lib/firmware/nxp/uartuart8987_bt.bin which is officially part of
linux-firmware and also in the same directory in the imx-firmware git
mentioned above.

Regarding license I found that snippet in nxp/SCR_nxp.txt:
Package:                   FwImage_8997, FwImage_8987, FwImage_8801,
FwImage_9098, FwImage_IW416, FwImage_IW612 Outgoing License:
LA_OPT_NXP_Software_License - Production Use, Section 2.3 applies
License File:              EULA.txt

Section 2.3 is:
2.3.        Additional Distribution License

But that is all legalese and I am not a lawyer... Best is of course
something officially added from NXP. No idea if it can be done
otherwise. How to make NXP add something?

Andreas
