+ The entry point of PE/COFF Image for the PEI Core.\r
+\r
+ This function is the entry point for the PEI Foundation, which allows the SEC phase\r
+ to pass information about the stack, temporary RAM and the Boot Firmware Volume.\r
+ In addition, it also allows the SEC phase to pass services and data forward for use\r
+ during the PEI phase in the form of one or more PPIs.\r
+ There is no limit to the number of additional PPIs that can be passed from SEC into\r
+ the PEI Foundation. As part of its initialization phase, the PEI Foundation will add\r
+ these SEC-hosted PPIs to its PPI database such that both the PEI Foundation and any\r
+ modules can leverage the associated service calls and/or code in these early PPIs.\r
+ This function is required to call ProcessModuleEntryPointList() with the Context\r
+ parameter set to NULL. ProcessModuleEntryPoint() is never expected to return.\r
+ The PEI Core is responsible for calling ProcessLibraryConstructorList() as soon as\r
+ the PEI Services Table and the file handle for the PEI Core itself have been established.\r
+ If ProcessModuleEntryPointList() returns, then ASSERT() and halt the system.\r
+\r
+ @param SecCoreData Points to a data structure containing information about the PEI\r
+ core's operating environment, such as the size and location of\r
+ temporary RAM, the stack location and the BFV location. \r
+\r
+ @param PpiList Points to a list of one or more PPI descriptors to be installed\r
+ initially by the PEI core. An empty PPI list consists of a single\r
+ descriptor with the end-tag EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST.\r
+ As part of its initialization phase, the PEI Foundation will add\r
+ these SEC-hosted PPIs to its PPI database such that both the PEI\r
+ Foundation and any modules can leverage the associated service calls\r
+ and/or code in these early PPIs.\r
