+Module Name:
+
+  Runtime.c
+
+Abstract:
+
+  Runtime Architectural Protocol as defined in the DXE CIS
+
+  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 fixup 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.

+  The EFI_SECURITY_ARCH_PROTOCOL (SAP) is used to abstract platform-specific 
+  policy from the DXE core response to an attempt to use a file that returns a 
+  given status for the authentication check from the section extraction protocol.  
+
+  The possible responses in a given SAP implementation may include locking 
+  flash upon failure to authenticate, attestation logging for all signed drivers, 
+  and other exception operations.  The File parameter allows for possible logging 
+  within the SAP of the driver.
+
+  If File is NULL, then EFI_INVALID_PARAMETER is returned.
+
+  If the file specified by File with an authentication status specified by 
+  AuthenticationStatus is safe for the DXE Core to use, then EFI_SUCCESS is returned.
+
+  If the file specified by File with an authentication status specified by 
+  AuthenticationStatus is not safe for the DXE Core to use under any circumstances, 
+  then EFI_ACCESS_DENIED is returned.
+
+  If the file specified by File with an authentication status specified by 
+  AuthenticationStatus is not safe for the DXE Core to use right now, but it 
+  might be possible to use it at a future time, then EFI_SECURITY_VIOLATION is 
+  returned.
+
+  @param  This             The EFI_SECURITY_ARCH_PROTOCOL instance.
+  @param  AuthenticationStatus 
+                           This is the authentication type returned from the Section
+                           Extraction protocol. See the Section Extraction Protocol
+                           Specification for details on this type.
+  @param  File             This is a pointer to the device path of the file that is
+                           being dispatched. This will optionally be used for logging.
+
+  @retval EFI_SUCCESS           The file specified by File did authenticate, and the
+                                platform policy dictates that the DXE Core may use File.
+  @retval EFI_INVALID_PARAMETER Driver is NULL.
+  @retval EFI_SECURITY_VIOLATION The file specified by File did not authenticate, and
+                                the platform policy dictates that File should be placed

+                                with a call to the Trust() DXE Service.
