20 Transfers control to DxeCore.
22 This function performs a CPU architecture specific operations to execute
23 the entry point of DxeCore with the parameters of HobList.
24 It also installs EFI_END_OF_PEI_PPI to signal the end of PEI phase.
26 @param DxeCoreEntryPoint The entry point of DxeCore.
27 @param HobList The start of HobList passed to DxeCore.
