Greetings! I am trying to submit bluetooth firmwares (BCM4329B1.*,*.hcd and BCM4330B1.*,*.hcd) and wifi calibration files (brcmfmac4329-sdio.*,*.txt and brcmfmac4329-sdio.*,*.txt) from a few Tegra 2 and Tegra 3 based devices into linux-fimware. I have faced ambiguous license issue since those files were part of Android Images of different vendors. Those vendors did not provide a license nor for android images, not for these files. Maybe you can clarify licensing of these files and you can suggest a way they could be accepted into linux-firmware?
Basically, the firmware files in linux-firmware fall under the license conditions that are in the repository. This means the firmware you want to submit would get a different license. The main reason is that the license in linux-firmware allows redistributing the firmware files which is an important aspect for linux distro maintainers.
So the device vendors would have to give their blessing. For these old chipsets they probably got it from Broadcom. I never had much contact with BT side so not sure who to contact about this.
Regarding the calibration files it is a bit awkward. There is a precedent as these have been published by community under GPL license. Broadcom never released those as they are board specific and the device vendor should provide them. So maybe you can submit those without any issue.
