eth0 and eth1 on C6678
C6678 has got EMAC1 and EMAC2. How to use eth0 and eth1 on C6678?
I'd suggest starting with the MCSDK 2.0. There's a Network Developers Kit (NDK) in the MCSDK 2.0
Here's a link to the MCSDK 2.0 info http://processors.wiki.ti.com/index.php/BIOS_MCSDK_2.0_User_Guide

It's no problem with eth0, but eth1 can not be detected after POST:

And eth1 can not be detected on Linux boot:

Where is eth1?
Can I work with eth1?
Actually, I'll assume that it's Ethernet Port 1 that you're connecting to. If you look through the EVM documentation you'll see that SGMII1 is connected via a switch to the RJ45 connector. Etherenet Port 0 (SGMII0) is put out to the AMC header for SGMII connection across an AMC backplane. You'd need to connect the SGMII up to another SGMII device such as a SGMII EMAC switch to communicate to that port on the EVM.
On the EVM,the SGMII Port 0is put out to the AMC header for backplane ethernet. Now I have another board which has 1000BASE-X Ethernet on the AMC header . Can I connect the SGMII Port 0 to the 1000BASE-X (SerDes Ethernet)port across an AMC backplane? If not ,what should I do ?
I'm wondering whether the SGMII port on the C6678 can connect to SerDes GbE(which mostly is 1000BASE-BX)?
The answer would be. Maybe. If the GbE uses SGMII for the media interface then yes. I believe if it's SerDes based then it would be SGMII, I'm not aware of another SerDes based GbE xMII. That said 1000BASE-BX is a fiber interface, so I'd suspect the chasis would have a SGMII to (whatever fiber uses) Switch. That's what I would suggest looking at to see what it is.
