To answer my own question:
Those two firmwares are calibration files and are optional (1).
Also, it looks like "Direct firmware load for ... failed with error -2"
does not imply that the missing firmware is required.
Thank you to "didier gaumet <didier.gaumet@gmail.com>" for clearing (2)
up and to "Alexander V. Makartsev <avbetev@gmail.com>" for his help.
