What version of u-boot are you using? There was a patch around Feb. 24th
that fixed some things in the ethernet driver for u-boot. Although since
you seem to have the TSEC ports working it seems you have the latest
version.

U-boot does not use interrupts for networking, it just uses polling. How
are you determining you are seeing interrupts from the PHYs and not the
FCC?

I have not attempted to use the FCC in u-boot but I have it working in
Linux, well sort of anyways... it is going extremely slow and I am still
investigating that. That being said I don't think u-boot has support for
using the FCC, so what changes did you make to get u-boot?
