1. For LoadImage() service, EFI_ACCESS_DENIED return status is added, and EFI_SECURITY_VIOLATION return status description is updated. Meanwhile, EFI_PE32_IMAGE_PROTOCOL. LoadPeImage() in MdeModulePkg is also updated to match LoadImage() service. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11306 6f19259b-4bc3-4df7-8a09-765794883524

 | |

|                                 understood.
 | |
|   @retval EFI_DEVICE_ERROR      Image was not loaded because the device returned a read error.
 | |
|   @retval EFI_ACCESS_DENIED     Image was not loaded because the platform policy prohibits the 
 | |
|                                 image from being loaded. NULL is returned in *ImageHandle.
