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.
