   I guess it's been blindly copied over form drivers/ide/pci/siimage.c...

   Yet the order of events between IDE and libata drivers is different:
the old driver's resetproc() method is called just after the twiddling the bit on/off, the new driver calls ata_std_softreset() after the PCI config. register manipulation. However, since all it does is set 2 read-only bits, it should make no difference...

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 turn into ata_bmdma_drive_eh(ap, ata_std_prereset, ata_std_softreset, sil680_bus_reset, ata_std_postreset)... 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
that its simply not needed 8)

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