186 @param PpiList Points to a list of one or more PPI descriptors to be installed initially by the PEI core.
187 An empty PPI list consists of a single descriptor with the end-tag
188 EFI_PEI_PPI_DESCRIPTOR_TERMINATE_LIST. As part of its initialization
189 phase, the PEI Foundation will add these SEC-hosted PPIs to its PPI database such
190 that both the PEI Foundation and any modules can leverage the associated service

215 the evaluation stack. When that entry is poped from the evaluation
216 stack, the PPI is checked if it is installed. This method allows
217 some time savings as not all PPIs must be checked for certain
218 operation types (AND, OR).
