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.
