Look at LL-temac driver to xps_ll_temac_phy_ctrl function - there is
phy setting. In any driver version was checking for phy ID which is on ml505.
If you remove that "if" testing the behavior will be the same as petalinux one.
This is u-boot pain and pain of all u-boot net drivers. There is missing phy-lib
but good news is that currently one implementation is on u-boot mailing list.
When is stable, I'll take a look at it.

Michal
