Hi all,


           I am working on a P1023 integrated board. Where DTSEC2 connected to a Ethernet PHY (that goes via Serdes-lane 03.... / lanes numbers from 0 to 3) is working fine.


           But DTSEC1(that goes via SerDes lane 02) to ARM based marvel switch, without any PHY connection between them.


          I checked switch is working fine. SerDes-lane 02 connection is good.


          I removed the "auto negotiation enable" inorder to support phyless connection at uboot and still we have problem.


I removed TBICR_ANEG_ENABLE option from TBICR_ANEG_ENABLE macro
The edited one looks like this.
                TBICR_PHY_RESET \
/*              TBICR_ANEG_ENABLE     */
                | TBICR_FULL_DUPLEX \
                | TBICR_SPEED1_SET \


             Is there is any better ways to resolve the issue.
