/**
The entry point of PEI Foundation.
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. These PPI's
will be installed and/or immediately signaled if they are
notification type. 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.
@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.
