2010-03-12edac: mpc85xx mask ecc syndrome correctlyPeter Tyser
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.

2009-06-30edac: add DDR3 memory type for MPC85xx EDACYang Shi
Since some new MPC85xx SOCs support DDR3 memory now, so add DDR3 memory type for MPC85xx EDAC. Signed-off-by: Yang Shi <yang.shi@windriver.com> Cc: Doug Thompson <norsk5@yahoo.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
