Personally, I just skip all firmware/RF configuration (which works thanks
to commit 4fb7b98c7be3 ("nfc: s3fwrn5: skip the NFC bootloader mode")).
That way, S3FWRN5 just continues using the proper configuration
that was loaded by the vendor drivers at some point. :)

But isn't that configuration lost after power off?

I don't know exactly but I don't think it's lost. At least the firmware
and rfreg configuration seem to be preserved since I've never provided
the driver with the necessary firmware. It just works without :)
