   In salvator-common.dtsi most probably -- it has the PHY data for Ether AVB.

   Well, r8a779{5|6}.dtsi also have phy-mode = "rgmii-txid" (which was unjustified
in my current understanding). Thus such board override wouldn't hurt them. But we lack
a patch modifying salvator-common.dtsi in htis series, so I'm now thinking a respin of
this series is needed anyway... sorry for being unclear. :-)
