/** | |
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. | |
