| @retval EFI_SUCCESS The image was loaded successfully. |
| @retval EFI_OUT_OF_RESOURCES There was not enough memory. |
| @retval EFI_LOAD_ERROR There was no supported image in the file. |
| @retval EFI_INVALID_PARAMETER FileHandle was not a valid firmware file handle. |
| @retval EFI_INVALID_PARAMETER EntryPoint was NULL. |
| @retval EFI_UNSUPPORTED An image requires relocations or is not |
| memory mapped. |
| @retval EFI_WARN_BUFFER_TOO_SMALL |
| There is not enough heap to allocate the requested size. |
| This will not prevent the XIP image from being invoked. |
