+/**
+ The entry point of PE/COFF Image for the PEI Core.
+
+ This function is the entry point for the PEI Foundation, which allows the SEC phase
+ to pass information about the stack, temporary RAM and the Boot Firmware Volume.
+ In addition, it also allows the SEC phase to pass services and data forward for use
+ during the PEI phase in the form of one or more PPIs.
+ There is no limit to the number of additional PPIs that can be passed from SEC into
+ the PEI Foundation. As part of its initialization phase, the PEI Foundation will add
+ these SEC-hosted PPIs to its PPI database such that both the PEI Foundation and any
+ modules can leverage the associated service calls and/or code in these early PPIs.
+ This function is required to call ProcessModuleEntryPointList() with the Context
+ parameter set to NULL. ProcessModuleEntryPoint() is never expected to return.
+ The PEI Core is responsible for calling ProcessLibraryConstructorList() as soon as
+ the PEI Services Table and the file handle for the PEI Core itself have been established.
+ If ProcessModuleEntryPointList() returns, then ASSERT() and halt the system.
+
+ @param SecCoreData Points to a data structure containing information about the
+ PEI core's operating environment, such as the size and
+ location of temporary RAM, the stack location and the BFV
+ location.
+
+ @param PpiList Points to a list of one or more PPI descriptors to be
+ installed initially by the PEI core. An empty PPI list
+ consists of a single descriptor with the end-tag
+ EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST.
+ As part of its initialization phase, the PEI Foundation will
+ add these SEC-hosted PPIs to its PPI database, such that both
+ the PEI Foundation and any modules can leverage the associated
+ service calls and/or code in these early PPIs.
