I am trying to interface a third party GMAC with the on-board PHY of Genesys2 board. I am trying to write a uboot driver for the GMAC on the Genesys2 board. I want to know the base address of the PHY. I was initially trying to set the PHY address as 0x00001 from the reference manual and trying to read the PHY ID1 (0x2) and PHY ID2 (0x3) registers. However, I am only getting 0x0000 instead of the default values mentioned in the datasheet of the Realtek RTL8211E-VL.
