[U-Boot] ksz9021 phy support
Hi Troy,
is here any specific reason for the "disable_giga" switch in the ksz9021 phy driver? We're just having some issues here, most of the times we don't get the link up with a gigabit connection. Anything else that caused trouble on your side, apart from the PHY ID mess?

The first versions of the SabreLite had an hardware issue:
"The current schematic has the center tap pin 9 of the MAG/JAC USB combo to 3.3 filtered supply. Letting this pin float solves the problem."
