I looked at the datasheet and erase_sector_39sf020() is totally and 

completely wrong. It was a straight cut'n'paste from SST 28SF040 code
and the person doing the cut'n'paste didn't even bother to check the
data sheet. The SST 39SF020 is completely incompatible with the 28SF040.

No need for replacement. According to the data sheet, standard JEDEC
commands will work and we have those commands in the tree already.
