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 think you are getting a reset yes, maybe your FPGA loses its programming or something similar ?
I'll pick this up on ppc and u-boot mailing list with new info, especially with the ppc4xx maintainers.
CC me, Ben.
