The following patch is needed to correctly assign the IRQs for the gianfar driver on the MPC8313ERDB-revc boards. ERR and TX are swapped as well as the interrupt lines for the two devices.
And it will incorrectly assign them on older revisions of the chip.
We really should have a u-boot fixup based on SVR.
Roland, is it possible for you to test this u-boot patch?:

mpc8313e erratum IPIC1 swapped TSEC interrupt ID numbers on rev. 1 h/w (see AN3545). The base device tree in use has rev. 1 ID numbers, so if on Rev. 2 (and higher) h/w, we fix them up here.
