Progress on this issue:

I found out that re-programming the end point FPGA again *just* after
*uboot* read it, and before Linux kernel has started, makes the end
point appear properly.

Either u-boot leaves the end point in bad state, or the root complex
reset also requires an end point reset. (or a third option I could not
think of yet).

I'll pick this up on ppc and u-boot mailing list with new info,
especially with the ppc4xx maintainers.

Consider this thread closed.

Thanks for ignoring my ranting :-)
