13  * Note: For P5040, the fourth SerDes bank (with two lanes) is on SerDes2, but
14  * U-Boot only supports one SerDes controller.  Therefore, we ignore bank 4 in
15  * this table.  This works because most of the SerDes code is for errata
16  * work-arounds, and there are no P5040 errata that effect bank 4.
