Thanks,
So my concerns are 2 fold:
1) Practical:
The brcmfmac4*-sdio.txt and brcmfmac4*-pci.txt files are nvram
files (which replace having an actual eeprom on the board)
are board specific, I've been discussing with upstream to modify
the driver to load these nvram files using a board specific name.
This never got very far because I never got permission to
redistribute the nvram files for the board which I have, see
point 2 below.
I believe that at a minimum these patches should be modified
to drop the .txt files for now until we've added a mechanism
for the driver to load a board specific version (using DMI
strings on x86 and info from DT on ARM) and then they should
be upstreamed under the board-specific filename.
2) Licensing
I've been in contact with Arend Van Spriel from Broadcom about
permission to redistribute nvram files and the files now being
licensed under the GPL contradicts with what I've been told.
This time around the matching actual firmware files are being
released under the Cypress license, which suggest ownership
of the wifi firmware has been passed to Cypress. So maybe
Cypress is ok with this, but we should double check that.
Also I'm not sure if that Cypress now owning the wifi
firmware copyright is true for all wifi controller models for
which these patches contain updated firmware versions...
I've also added Chi-Hsien Lin from Cypress to the Cc.
Arend and Chi-Hsien can you clarify the licensing situation
here, is it correct that the wifi and bluetooth firmware
files offered by Murata here:
https://github.com/murata-wireless
Fall under the Cypress license and that the nvram files
offered there may be distributed under the GPL?
Regards,
Hans
