 Subject: [PATCH] Platform/ARM/N1Sdp: Reserve OP-TEE Region from UEFI
 
 To enable cache on N1SDP, OP-TEE has to be moved
 to run from DDR4 memory. Since this memory is
 known to application side, it must be reserved
 
-Upstream-Status: Pending (not yet submitted to upstream)
+Upstream-Status: Inappropriate [will not be submitted as it's a workaround to address hardware issue]
