No Idea how MTK factory calibration data is individual per-device.

If it's possible, I'd like to propose a archive of the radio-calibration / MAC-Address partition.

So this would be used to enable people download their calibration data for their serial-number and
make it "unbrickable" with an SPI clamp.

What do you think?
