2017-10-16soc/intel/common: sanity check ebda signatureAaron Durbin
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.

2015-08-14intel/common: fix stage_cache_external_region()Aaron Durbin
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.
