Do a HW initialize to the PHY ( via RSTC ) and setup clocks & PIOs This should be called only once to initialize the PHY pre-settings.

The PHY address is reset status of CRS,RXD[3:0] (the emacPins' pullups). The COL pin is used to select MII mode on reset (pulled up for Reduced MII) The RXDV pin is used to select test mode on reset (pulled up for test mode) The above
pins should be predefined for corresponding settings in resetPins The EMAC peripheral
pins are configured after the reset done. Return 1 if RESET OK, 0 if timeout.
