[U-Boot] u-boot vs. Cavium 5010 pci init

[sywang]

Andreas, 

Now the key is that I am not sure if the board can work or not. 

Who had the similar experience ( debugged the board with CN5010)? Please
email to me. Thanks for your help. 


Thanks!
Shuyou

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 ...
