With SIDPR SCR access enabled, ata_piix ports can access PHY events and errors and can also be hardreset which is important as in rare cases hardreset is necessary to recover from error conditions. Changes from the last take [L] are... * Dropped first two accepted patches. * Re-generated against the current upstream. This patchset is against the current libat-dev#upstream (2de8d964). Thanks. -- tejun [L] http://thread.gmane.org/gmane.linux.ide/26780
