The problem is that the whole cavium code is proprietary. They develop their cvmx code completely out of tree and link the code at file basis into a specific tree with more proprietary changes. Since this code is completely unknown to the community the community can not help you solving SW issues. Therefor go and ask cavium for support.
On the other hand you may ask cavium to push their proprietary code upstream. Then it would be possible (some day) to solve those issues within the community.
The third chance is to take your documentation, the current code and current u-boot tree and begin to implement open source support for your device.

If you have started building your own u-boot for a working device/board then I guess it is a SW issue (missing support in mainline). If you have received a _not_ working device/board it may be HW related ...
