yes, it would. "software write protection" is what u-boot offers today -- the
software checks the addresses before allowing writes. hardware write
protection is where u-boot puts out the write command anyways the request is
rejected by the hardware. just because you have a knob to toggle the hardware
write protection doesnt mean it is no longer protected in hardware.
