+Subject: [PATCH] arm/corstone1000: esrt support
+
+The implementation is platform specific and would require
+change in future.
+
+The patch should not be upstreamed as it is to the u-boot.
+Redesign of FMP protocol for ESRT and Capsule Update interface
+is to be considered in the future.
+
+Signed-off-by: Satish Kumar <satish.kumar01@arm.com>
+Upstream-Status: Inappropriate [Redesign of FMP protocol for ESRT and Capsule update interface is required]
