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