+/**
+ 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
+ in the untrusted state. A file may be promoted from
+ the untrusted to the trusted state at a future time
+ with a call to the Trust() DXE Service.
+ @retval EFI_ACCESS_DENIED The file specified by File did not authenticate, and
+ the platform policy dictates that File should not be
+ used for any purpose.
