fix-allow-full-sd-voltage-range-selection.patch
Until now we just drove the SD Card at 3.3V all the time. But in
fact we can do better, and use a voltage negotiated with the
SD Card itself.
With the shipping 512MB Sandisk SD Card, 2.7V is negotiated which
gives 1.7dBm reduction in power on all the SD Card lines and should
further reduce GPS perturbation during SD Card usage.
