Correct. It can only report this kind of error. It is not correctable.

DDR controller can only report the error. I don't believe EDAC driver can do more. For the same reason I said we can leave RXFE as is, even for e500v1 case (with RIO or PCI is enabled). Nothing can be done with uncorrectable error. York
