71871514 | 26 | The entry point of PE/COFF Image for the PEI Core.\r |
c7d265a9 | 27 | \r |
71871514 | 28 | This function is the entry point for the PEI Foundation, which allows the SEC phase\r |
29 | to pass information about the stack, temporary RAM and the Boot Firmware Volume.\r | |
30 | In addition, it also allows the SEC phase to pass services and data forward for use\r | |
31 | during the PEI phase in the form of one or more PPIs.\r | |
32 | There is no limit to the number of additional PPIs that can be passed from SEC into\r | |
33 | the PEI Foundation. As part of its initialization phase, the PEI Foundation will add\r | |
34 | these SEC-hosted PPIs to its PPI database such that both the PEI Foundation and any\r | |
35 | modules can leverage the associated service calls and/or code in these early PPIs.\r | |
36 | This function is required to call ProcessModuleEntryPointList() with the Context\r | |
37 | parameter set to NULL. ProcessModuleEntryPoint() is never expected to return.\r | |
38 | The PEI Core is responsible for calling ProcessLibraryConstructorList() as soon as\r | |
39 | the PEI Services Table and the file handle for the PEI Core itself have been established.\r | |
40 | If ProcessModuleEntryPointList() returns, then ASSERT() and halt the system.\r | |
41 | \r | |
42 | @param SecCoreData Points to a data structure containing information about the PEI\r | |
43 | core's operating environment, such as the size and location of\r | |
44 | temporary RAM, the stack location and the BFV location. \r | |
45 | \r | |
46 | @param PpiList Points to a list of one or more PPI descriptors to be installed\r | |
47 | initially by the PEI core. An empty PPI list consists of a single\r | |
48 | descriptor with the end-tag EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST.\r | |
49 | As part of its initialization phase, the PEI Foundation will add\r | |
50 | these SEC-hosted PPIs to its PPI database such that both the PEI\r | |
51 | Foundation and any modules can leverage the associated service calls\r | |
52 | and/or code in these early PPIs.\r | |
