Routine Description:
Relocate the PEIM into memory.
Once load protocol becomes available, relocate our PEIM into memory.
The primary benefit is to eliminate the blackout window that we would have in
the memory log between the end of PEI and the status code DXE driver taking
control. If we don't do this, we cannot determine where our memory journal
is located and cannot function.
A second benefit is speed optimization throughout DXE.
Arguments:
PeiServices - General purpose services available to every PEIM.
NotifyDescriptor - Information about the notify event.
Ppi - Context
Returns:
EFI_SUCCESS This function always returns success.
