I seriously doubt that is going to do anything at all, all 4 these keywords do not
show up when running strings on brcmfmac43362-sdio.bin, where as all the
keywords used in the brcmfmac43362-sdio.txt shipped with the android on ap6210
equipped boards do show up, confirming that the keywords are encoded in plain text
in the firmware file.

Let me know if want me to give it a try anyways and I'll do so.

Perhaps these keywords need a newer firmware version then the one in the
linux-firmware repository ?
