/**
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 Do nothing and return.
