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.
