c714137d95 soc/intel/common: sanity check ebda signature
It's possible for chipsets utilizing ebda to cache the cbmem_top()
value to be called prior to the object being entirely setup. As
such it's important to check the signature to ensure the object
has been initialized. Do that in a newly introduced function,
retrieve_ebda_object(), which will zero out the object if the
signature doesn't match.

721d1b3090 soc/intel/skylake: Fix top_of_ram calculation
FSP 2.0 implementation conditionally sets PMRR base based on
EnableC6Dram UPD. Therefore, handle the case of the PMRR base not being
set since FSP 2.0 changed behavior from FSP 1.1 implementation.

If prmrr base is non-zero value, then top_of_ram is prmrr base.

If Probeless trace is enabled, then deduct trace memory size from
calculated top_of_ram.

1222a73205 skylake: Add initial FSP2.0 support
Add Initial pieces of code to support fsp2.0 in skylake keeping
the fsp1.1 flow intact.

The soc/romstage.h and soc/ramstage.h have a reference to
fsp driver includes, so split these header files for
each version of FSP driver.

Add the below files,
car_stage.S:
	Add romstage entry point (car_stage_entry).
	This calls into romstage_fsp20.c and aslo handles
	the car teardown.
romstage_fsp20.c:
	Call fsp_memory_init() and also has the callback
	for filling memory init parameters.

Also add monotonic_timer.c to verstage.

With this patchset and relevant change in kunimitsu mainboard,
we are able to boot to romstage.

c43d417039 intel/common: fix stage_cache_external_region()
The stage_cache_external_region() calculation is actually
dependennt on the properties of the chipset. The reason
is that certain regions within the SMRAM are used for
chipset-specific features. Therefore, provide an API
for abstracting the querying of subregions within
the SMRAM.

The 3 subregions introduced are:

SMM_SUBREGION_HANDLER - SMM handler area
SMM_SUBREGION_CACHE - SMM cache region
SMM_SUBREGION_CHIPSET - Chipset specific area.

The subregions can be queried using the newly
added smm_subregion() function.

Now stage_cache_external_region() uses smm_subregion()
to query the external stage cache in SMRAM, and this
patch also eliminates 2 separate implementations of
stage_cache_external_region() between romstage and
ramstage.
