As a consequence of this, the following errors show up when booting Linux: wiz bus@f0000:phy@f000000: probe with driver wiz failed with error -12 ... wiz bus@f0000:phy@f010000: probe with driver wiz failed with error -12 To not only fix the above, but also, in order to follow the convention of disabling device-tree nodes in the SoC file and enabling them in the board files for those boards which require them, disable "serdes_wiz0" and "serdes_wiz1" device-tree nodes.
