The code indeed does seem meaningless. For the libata it could make sense to
set bit 2 for the hardreset -- but then sil680_error_handler() needs to be

For the legacy driver, this function needs to be converted to something
sane too...
I think the evidence based upon years of highly reliable siimage usage is

I would think so as well but was not sure about the SStatus reg. read at
