No more hang on DMI init when wait for DMI is re-enabled. Previously the virtual channel arbitration table was not being set up in the south/north bridges causing invalid DMI state.

2016-08-09x4x: make preallocated IGD memory a cmos optionArthur Heymans
This allows to set the preallocated memory for the IGD on x4x using a cmos option. If no cmos option is found a default value of 64M is used. TESTED most options on ga-g41m-es2l with 2G dimm in one slot and 2x2G. 352M also works in contrast with gm45 where it is known to cause issues with certain ram combinations.

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.

2016-02-10Kconfig: Move defaults for CBFS_SIZEMartin Roth
We want the question for CBFS size to be next to the rom size in the mainboard directory, but that doesn't seem to work for how people want to set the defaults. Instead of having the list of exceptions to the size, just set the defaults at the end of kconfig. - Move the defaults for chipsets not setting HAVE_INTEL_FIRMWARE into the chipset Kconfigs (gm45, nehalem, sandybridge, x4x) - Override the default for HAVE_INTEL_FIRMWARE on skylake. - Move the HAVE_INTEL_FIRMWARE default setting into the firmware Kconfig file - Move the location of the default CBFS_SIZE=ROM_SIZE to the end of the top level kconfig file, while leaving the question where it is. Test=rebuild Kconfig files before and after the change, verify that they are how they were intended to be. Note: the Skylake boards actually changed value, because they were picking up the 0x100000 from HAVE_INTEL_FIRMWARE instead of the 0x200000 desired. This was due to the SOC_INTEL_SKYLAKE being after the HAVE_INTEL_FIRMWARE default. Affected boards were: Google chell, glados, & lars and Intel kunimitsu.
