2018-04-16nb/intel/sandybridge: support more XMP timingsDan Elkouby
Tested with a pair of GSkill F3-1866C9-8GSR. This makes sure in particular that we honor the CMD rate requested by the XMP profile. This memory kit needs a CMD rate of 2 to be stable at DDR3-1600 and up, even though it passes training at 1. Also respect requested CWL to match vendor firmware and for a potential increase in performance. The tested kit requests a tighter value than the per-frequency table provides and has shown to be stable using that setting.

2017-08-10nb/intel/sandybridge/raminit: Add Kconfig option for fusesPatrick Rudolph
Add a new Kconfig option to ignore memory fuses that limit the maximum DRAM frequency to be used. The option is disabled by default and should only enabled by experienced users as it might decrease system stability or prevent a successful RAM training. Remove conflicting devicetree settings.

2017-06-22nb/intel/sandybridge/raminit: Fix dual DIMM command ratePatrick Rudolph
On boards that are able to take two DIMMs per channel the command rate should be 2T. It is possible to use 1T with load reduced "1T" DIMMs, but it's not clear how to detect those DIMMs. Raminit might fail for those who do not have such DIMMS installed. Hardcode command rate of 2T to make sure raminit works on dual DIMM per channel boards (currently only desktop boards). The command rate of 1T is still tested if only 1 DIMM per channel is present. Will decrease performance on quad slot mainboards, if two DIMMs are installed in one channel and previously 1T have been selected. Tested on ASRock B75 Pro3-M.

Move odt stretch into own function. Apply workaround on SandyBridge C-stepping CPU only. Apply odt stretch on all other CPU types. Don't depend on empty DIMM detection, as in case one slot is empty ref_card_offset is zero.
