Hello everyone we have made our own custom board with some revision DM6446.I
have sucessfully ported the linux on that board using the open source git
kernel but in our new board we have done revision.The PHY that we previously
used was LAN 8700 now we have changed the PHY to LAN8710 but the PHY does not
gets detected.
The ETH PHY driver in the u-boot is assumed to be generic so it should detect
the PHY whenever it boots up it says GENERIC ETH PHY @ 00.
Here is my u-boot log
TI UBL Version: 1.31
Booting Catalog Boot Loader
BootMode = NAND
Starting NAND Copy...

Addr and/or reg may be ranges, e.g. 2-7.
U-Boot > mii write 2 2 2
U-Boot > mii read 2 2
Error reading from the PHY addr=02 reg=02

Do i need to add the support for the new PHY in u-boot what further
modifications i will have to do in the kernel to Add the support for LAN 8710.
Regard's
