Exactly. And at least one board (MPC8568E-MDS) using this feature: UECs are using PHYs placed on the TSEC's MDIO bus. This is hardware configurable, and could be contrariwise: TSECs can use PHYs that are under control of UEC MDIO bus controller. That's why we're naming PHYs as bus:phyid. -- Anton Vorontsov email: [EMAIL PROTECTED] backup email: [EMAIL PROTECTED] irc://irc.freenode.net/bd2 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
