2016-05-02nb/amd/mct_ddr3: Only initialize ECC bits onceTimothy Pearson
The ECC check bits of all ECC DIMMS were inadvertently initialized twice in the same routine, significantly delaying startup. Part of this was related to an obsolete MCA workaround that has been fixed through multiple commits, therefore the workaround is no longer needed. Only initialize the ECC check bits once.

During DQS receiver enable cycle training on Family 15h platforms the read data timing registers were inadvertently set to zero on every lane training attempt. Ensure that the read data timing registers are correctly set after each lane is trained in receiver enable cycle training. This allows more than one RDIMM to function on a given DCT channel.

2016-04-11and/nb/mct_ddr3: Pack all structures passed to ramstage and set alignmentTimothy Pearson
Two of the MCT data structures passed as substructures to ramstage were not packed, and additionally no alignment was specified. On at least SP5100-based platforms, specifying packed with no alignment caused boot failure dependent on the exact compiled binary layout (LPC hang). Specifying the alignment and packing the remaining structures appears to have resolved the remaining LPC hang issues on the KGPE-D16. Note that packing the remaining structures alone was not sufficient to eliminate the hang, however removing the packed attribute entirely (during debugging) did resolve the hang at the expense of potential problems in ramstage.

Under certain conditions, not elucidated in the BKDG, an extra memclock of CAS write latency is required. The only reliable way I have found to detect when this is required is to try training without the delay, and if DQS position training fails, adding the delay and retraining. This is probably related in some form or another to the badly broken DQS Write Early algorithm given in the BKDG.

2015-11-15northbridge/amd/amdmct: Reduce maximum number of DDR3 DIMMsTimothy Pearson
CAR space on certain platforms is nearly full. This prevents the addition of necessary RAM initialization features such as x4 DIMM support. As the DIMM SPD cache uses a sizeable amount of CAR RAM, reducing it would free up a significant amount of CAR RAM. DDR3-based AMD platforms only support up to 3 physical DIMMs on each channel (6 per node). Reduce the maximum number of DIMMs on a node from 8 to 6 accordingly.
