83Routine Description:\r
84\r
85 The entry routine to Pei Core, invoked by PeiMain during transition\r
86 from SEC to PEI. After switching stack in the PEI core, it will restart\r
87 with the old core data.\r
88\r
89Arguments:\r
90\r
91 PeiStartupDescriptor - Information and services provided by SEC phase.\r
92 OldCoreData - Pointer to old core data that is used to initialize the\r
93 core's data areas.\r
94\r
95Returns:\r
96\r
97 This function never returns\r
98 EFI_NOT_FOUND - Never reach\r
