+/** @file

+  This file implements Runtime Architectural Protocol as defined in the

+  Platform Initialization specification 1.0 VOLUME 2 DXE Core Interface.

+

+  This code is used to produce the EFI runtime virtual switch over

+

+  THIS IS VERY DANGEROUS CODE BE VERY CAREFUL IF YOU CHANGE IT

+

+  The transition for calling EFI Runtime functions in physical mode to calling

+  them in virtual mode is very very complex. Every pointer in needs to be

+  converted from physical mode to virtual mode. Be very careful walking linked

+  lists! Then to make it really hard the code it's self needs be relocated into

+  the new virtual address space.

+

+  So here is the concept. The code in this module will never ever be called in

+  virtual mode. This is the code that collects the information needed to convert

+  to virtual mode (DXE core registers runtime stuff with this code). Since this

+  code is used to fix up all runtime images, it CAN NOT fix it's self up. So some

+  code has to stay behind and that is us.

+

+  Also you need to be careful about when you allocate memory, as once we are in

+  runtime (including our EVT_SIGNAL_EXIT_BOOT_SERVICES event) you can no longer

+  allocate memory.

+

+  Any runtime driver that gets loaded before us will not be callable in virtual

+  mode. This is due to the fact that the DXE core can not register the info

+  needed with us. This is good, since it keeps the code in this file from

+  getting registered.

+

+

+Revision History:

+

+  - Move the CalculateCrc32 function from Runtime Arch Protocol to Boot Service.

+  Runtime Arch Protocol definition no longer contains CalculateCrc32. Boot Service

+  Table now contains an item named CalculateCrc32.
