/**
The entry point of PE/COFF Image for the PEI Core, that has been hijacked by this
SEC that sits on top of an OS application. So the entry and exit of this module
has the same API.
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.
