With a 64-bit wide data bus only the lowest 8-bits of the ECC syndrome are relevant. With a 32-bit wide data bus only the lowest 16-bits are relevant on most architectures. Without this change, the ECC syndrome displayed can be mildly confusing, eg: EDAC MPC85xx MC1: syndrome: 0x25252525 When in reality the ECC syndrome is 0x25. A variety of Freescale manuals say a variety of different things about how to decode the CAPTURE_ECC (syndrome) register. I don't have a system with a 32-bit bus to test on, but I believe the change is correct. It'd be good to get an ACK from someone at Freescale about this change though.
