+
+ Routine Description:
+ Causes the driver to load a specified file.
+
+ Arguments:
+ This - Protocol instance pointer.
+ FilePath - The device specific path of the file to load.
+ BootPolicy - Should always be FALSE.
+ BufferSize - On input the size of Buffer in bytes. On output with a return
+ code of EFI_SUCCESS, the amount of data transferred to
+ Buffer. On output with a return code of EFI_BUFFER_TOO_SMALL,
+ the size of Buffer required to retrieve the requested file.
+ Buffer - The memory buffer to transfer the file to. IF Buffer is NULL,
+ then no the size of the requested file is returned in
+ BufferSize.
+
+ Returns:
+ EFI_SUCCESS - The file was loaded.
+ EFI_UNSUPPORTED - BootPolicy is TRUE.
+ EFI_INVALID_PARAMETER - FilePath is not a valid device path, or
+ BufferSize is NULL.
+ EFI_NO_MEDIA - No medium was present to load the file.
+ EFI_DEVICE_ERROR - The file was not loaded due to a device error.
+ EFI_NO_RESPONSE - The remote system did not respond.
+ EFI_NOT_FOUND - The file was not found
+ EFI_ABORTED - The file load process was manually cancelled.
+ EFI_BUFFER_TOO_SMALL - The BufferSize is too small to read the current
+ directory entry. BufferSize has been updated with
+ the size needed to complete the request.
