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