Move out PCS handling from piix_sata_prereset() into piix_sata_present_mask() and use it from newly implemented piix_sata_softreset(). Class codes for devices which are indicated to be absent by PCS are cleared to ATA_DEV_NONE. This fixes ghost device problem reported on ICH6 and 7 (and probably 8). This patch moves PCS handling from prereset to softreset, which makes ata_piix perform softreset even when PCS indicates no device. Signed-off-by: Tejun Heo <htejun@xxxxxxxxx>
