+ This function is invoked by the PEI Foundation.\r
+ The PEI Foundation will invoke this service when there are\r
+ no additional PEIMs to invoke in the system.\r
+ If this PPI does not exist, it is an error condition and\r
+ an ill-formed firmware set. The DXE IPL PPI should never\r
+ return after having been invoked by the PEI Foundation.\r
+ The DXE IPL PPI can do many things internally, including the following:\r
+ - Invoke the DXE entry point from a firmware volume\r
+ - Invoke the recovery processing modules\r
+ - Invoke the S3 resume modules\r
