/**
|
|
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.
