The following words are got from SB700 rpr. It seems that the phy settings have something to do with the eSATA.
SATA_PCI_config 0x01B48017 SATA_PCI_config 0x01B48019 SATA_PCI_config 0x01B48016 SATA_PCI_config 0x01B48016 SATA_PCI_config 0x01B48016 SATA_PCI_config 0x01B48016 SATA GENI PHY ports setting, Pre-emphasis setting, and GENII PHY setting enable setup for port [0~5] This setting is for the Travelly board. Since it's port0 and port1are eSATA ports, the PCI_config 0x88 and 0x8C have different settings than the rest of the ports. For non-esata port, the setting should be 0x01B48016. For shinner board, SATA_PCI_config 0x88/8C/90/94/98/9C [31:0] = 0x01B48016. SATA_PCI_config 0xA0 [15:0] = 0xA09A SATA_PCI_config 0xA2 [15:0] = 0xA09F SATA_PCI_config 0xA4 [15:0] = 0xA07A SATA_PCI_config 0xA6 [15:0] = 0xA07A SATA_PCI_config 0xA8 [15:0] = 0xA07A SATA_PCI_config 0xAA [15:0] = 0xA07A SATA GEN II PHY port setting for port [0~5]. This setting is for the Travelly board. Since it's port0 and port1 are eSATA ports, the PCI_config 0xA0 and 0xA2 have different settings than the rest of the ports. For non-esata port, the setting should be 0xA07A. For shinner board, SATA_PCI_config 0xA0/A2/A4/A6/A8/AA [15:0] = 0xA07A. I am not quite familiar with the attribute weak. It seems to be a good way.
