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