We traced the problem to the connection between MAC and PHY, and we have resolved it by instrumenting code and comparing the TBI and PHY initialization from u-boot to the Linux DPA code, and replacing some of the "magic numbers" we found in the driver with "magic numbers" we know to work. OUCH! We spent an inordinate amount of effort in trying to understand the undocumented code/tree, but I am convinced that the device-tree approach to embedded boards is a very valuable approach, and will ultimately solve many more problems than it creates short term. Again, your information was of great assistance, and I look forward to being able to pay forward the same kind of assistance in the future.
