I've checked the TA bit. The TA bit is 11 which means the TA bit is not correct.
I changed the code to not verify the TA bit, It still returns all
ones. Then I printed out all the values get. All that I get is 1. I'm
going to check the MDIO with a oscilloscope.
Thanks paul, you give me another way
Yes, the PHY address is correct, I've checked the schematics, and
2.6.22 is also using this PHY address.
The different between 2.6.22 and 2.6.32.6 is that:
In 2.6.22, we use arch/ppc/8260_io/fcc_enet.c as the driver. IMMR
address 0xf000 is directly used.
In 2.6.32.6, cpm2-fcc-enet driver is use

I tried to skip the turn around bit check in source, but the mii bus
still get the 0x PHYIDs.
I will check if there is any pull ups on mdio line.
Thank you.
