2016-07-27nb/intel/x4x: Fix CAS latency detection and max memory detectionDamien Zammit
Now hardcode maximum memory frequency capability to 800MHz, as all chipsets in x4x family support PC2-6400 according to the datasheet. CAS latency detection also relies on this, and has been cleaned up. Ram initialization does not work with FSB 1333MHz / DDR2 800MHz combination, so disable this combination for now, and reduce to 667MHz instead. Still don't know why this is the case, but FSB1333/667 works. These changes should now allow existing configurations to continue working, while providing support for previously unworking configurations, due to previous buggy CAS latency detection code.

2016-06-04gm45: enable setting all vram sizes from cmosArthur Heymans
Setting the size of the preallocated memory for the igd is done using a cmos parameter, gfx_uma_size. This was limited to a subset of all available sizes, that were already implemented elsewhere in the northbridge code. What this does is change the cmos parameter to 4 bits instead of 3 bits to accomodate all vram sizes. It also adds a sane default of 32mb that already was in place. The northbridge code that reads this cmos parameter is also changed for this new cmos settings. 352M is disabled since it causes issues on systems with 4GB or more ram. TEST: Build, flash target. Clear cmos by corrupting the checksum (nvramtool -c something). Set a desired value in gfx_uma_size using nvramtool. "dmesg | grep stolen" to see what is actually allocated.

2016-05-01nb/amd/mct_ddr3: Stop receiver enable cycle training after window foundTimothy Pearson
During receiver enable cycle training on Family 15h the entire range of possible delays is searched, even though the single passing window is often found nearly immediately. Skip the remainder of the delay range after the passing window has been located.

2016-05-01nb/amd/mct_ddr3: Do not constantly reset read data timing registers to 0Timothy Pearson
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.

2016-05-01nb/amd/mct_ddr3: Fix x4 DIMM receiver enable training on Fam15hTimothy Pearson
The existing Family 15h receiver enable training code stored temporary delay values in the wrong variables, leading to the requisite averaging of delays across nibbles not being applied. This in turn made x4 DIMMs less stable than they should have been. Store temporary nibble delay values in a dedicated array.

2016-04-28nb/amd/mct_ddr3: Restart system on training failure instead of using die()Timothy Pearson
DIMM training can sporadically fail due to external influences or various errata. In these cases, restarting to retry training is a more appropriate response than halting the system and requiring manual intervention.

2016-04-26nb/amd/mct_ddr3: Fix a number of minor errors in RDIMM setupTimothy Pearson
The existing RDIMM RC control word send routines were a hodgepodge of various AGESA chunks with different ways of handling the same task. Unify the control word chip select setup, use precise timing routines on Family 15h, fix a couple of incorrect masks, and add additional debugging statements. It is believed that this patch is cosmetic and does not significantly alter existing functionality.

2016-04-25nb/amd/mct_ddr3: Scale lane delays for each DIMM after MEMCLK changeTimothy Pearson
When more than one DIMM is installed on a DCT, only the first DIMM delay values are scaled to the new memory clock frequency after a memory clock change during write leveling. Store the previous memory clock of each DIMM during write leveling to ensure that every DIMM has its delay values rescaled.
