df6eb79a22 intel/x4x: Do not use scratchpad register for ACPI S3
If S3 support was implemented for this platform later on, use
romstage handoff structure instead.

9ae0985328 nb/intel/x4x: Fix underclocking of 800MHz DDR2 RAM
Previously, any 800MHz DIMMs were being slowed to 667MHz
for no reason other than there was a bug in the maximum
frequency detection code for the MCH.

68e1dcfdd9 nb/intel/x4x: Fix unpopulated value
Previously, 0x0 was the value being used for an unpopulated dimm
on spd[62], however some DDR2 dimms have 0x0 as a valid value.
Now use 0xff which is an unused value even on DDR2/DDR3.

a090ae04c2 nb/intel/x4x: Add DMI/EP init
The values were obtained from vendor bios at runtime.
I am not 100% sure of the sequence required to initiate them,
but guessed from the gm45 code.  There may be some status bytes
needed to be polled during the sequence that is missing,
but as I don't have bios writer's datasheet it's very hard
for me to know.

59ff3400b0 Kconfig: Move defaults for CBFS_SIZE
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.

5680fafb4d nb/intel/x4x: Move to early cbmem
Previously with errors in the ram init, early cbmem was disabled.
Now that the ram is working correctly, set as early cbmem platform
and update all (1) boards to use it.

Tested on GA-G41M-ES2L

9fb08f55a8 nb/intel/x4x: Fix memory hole with both channels populated
Previously, 0xa0000000 to 0xc0000000 needed to be reserved as
a non-usable memory hole because it would hang on memory i/o.

Memtest86+ now passes with no errors on both channels populated.
Tested on GA-G41M-ES2L with 2x2GiB sticks of ram.
