bb85f9eb73 Revert "AMD OemS3Save: refactor for Merlin Falcon"
This reverts commit d3deecdd9c.

Do not mix open-source AGESA and binary PI trees. Once you have
working S3 support for binaryPI platforms, add the adapted
oem_s3.c file as northbridge/amd/pi/oem_s3.c instead.

1eaaa0e446 southbridge/amd/sr5650: Add MCFG ACPI table support
As the southbridge largely controls the PCI[e] configuration space
this patch moves the resource allocation from the northbridge
to the southbridge when the extended configuration space region
is enabled.

f682d0028c amd/amdmct/mct_ddr3: Partially fix up registered DIMMs on Fam10h
Sufficient support has been added to allow booting with registered
DIMMs on the KGPE-D16 in certain slots.  ECC support needs additional
work; the ECC data lanes appear to cause boot failures in some slots.

dc4cb05763 nb/amd/mct_ddr3: Fix RDIMM errors due to undefined number of slots
The current code did not define the number of DIMM slots on the
mainboard, which lead to incorrect configuration values and
occassional training failure.

Add preliminary support for DIMM slot count configuration.

9597790571 northbridge/amd/amdmct: Reduce maximum number of DDR3 DIMMs
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.

11739a48ce northbridge/amd/amdmct/mct_ddr3: Work around strange phy training issue
AMD Opteron processors contain a very fragile phy phase detection circuit.
Additionally, the algorithm given in the BKDG does not function as intended;
this was verified both on real hardware via execution trace and on paper
with values read back from multiple CPUs and DIMMs.

As a result, the phy training algorithm given in the BKDG has been
replaced with a phy training algorithm developed at Raptor Engineering.
This particular patch is the first part of that algorithm; the code
is updated in future patches but this should exist in the historical
record in case something breaks down in the later sections of code.
