[U-Boot] kernel upgradation 2.6.23 to 2.6.35.13 with old U-boot 1.3.0 version

Hi,
I have MPC8313E-RDB board on which U-boot 1.3.0(along with patches) and kernel 2.6.23(along with patches) are running.
Now, i would like to upgrade the kernel from 2.6.23 to 2.6.35.13 with old U-boot 1.3.0(along with patches), i am facing problem in loading firmware and ethernet interfaces like "eth0/eth1 : are not attached to PHY".
Is that i have to upgrade also U-boot also to latest version? If so what version of u-boot is compatiable with linux kernel 2.6.35.13.
Please let me know what is the issue. ASAP.

This makes a lot of sense in any case.
If so what version of u-boot is compatiable with linux kernel 2.6.35.13.
Just use the latest version (top o git tree) or at least latest release, v2012.07.
Best regards,
