If Renesas could bother to spend the effort to be legally allowed to
include the firmware in linux-firmware, do we want to spend the effort
to maintain the support for this PCIe controller in mainline?

Is there even an example of a device driver that *requires* firmware
that is not in linux-firmware?

(I know of some device drivers that does not have firmware in
linux-firmware, but in that case the firmware is *optional*,
so the device driver still works even without loading an updated
firmware. For this patch series, the driver seems to error out if
request_firmware fails.)


Kind regards,
Niklas
