+Verified Boot
+-------------
+
+U-Boot supports an image verification method called "Verified Boot".
+This is a brief tutorial to utilize this feature for the UniPhier platform.
+You will find details documents in the doc/uImage.FIT directory.
+
+Here, we take LD20 reference board for example, but it should work for any
+other boards including 32 bit SoCs.
+
+1. Generate key to sign with
+
+  $ mkdir keys
+  $ openssl genpkey -algorithm RSA -out keys/dev.key \
+    -pkeyopt rsa_keygen_bits:2048 -pkeyopt rsa_keygen_pubexp:65537
+  $ openssl req -batch -new -x509 -key keys/dev.key -out keys/dev.crt
+
+Two files "dev.key" and "dev.crt" will be created.  The base name is arbitrary,
+but need to match to the "key-name-hint" property described below.
+
+2. Describe FIT source
+
+You need to write an FIT (Flattened Image Tree) source file to describe the
+structure of the image container.
+
+The following is an example for a simple usecase:
+
+---------------------------------------->8----------------------------------------
+/dts-v1/;
+
+/ {
+	description = "Kernel, DTB and Ramdisk for UniPhier LD20 Reference Board";
+	#address-cells = <1>;
+
+	images {
+		kernel@0 {
+			description = "linux";
+			data = /incbin/("PATH/TO/YOUR/LINUX/DIR/arch/arm64/boot/Image.gz");
+			type = "kernel";
+			arch = "arm64";
+			os = "linux";
+			compression = "gzip";
+			load = <0x82080000>;
+			entry = <0x82080000>;
+			hash@0 {
+				algo = "sha256";
+			};
+		};
+
+		fdt@0 {
+			description = "fdt";
+			data = /incbin/("PATH/TO/YOUR/LINUX/DIR/arch/arm64/boot/dts/socionext/uniphier-ld20-ref.dtb");

+			};

+			description = "ramdisk";
+			data = /incbin/("PATH/TO/YOUR/ROOTFS/DIR/rootfs.cpio");
+			type = "ramdisk";
+			arch = "arm64";
+			os = "linux";
+			compression = "none";
+			hash@0 {
+				algo = "sha256";
+			};
+		};
+	};
+
+	configurations {
+		default = "config@0";
+
+		config@0 {
+			description = "Configuration0";
+			kernel = "kernel@0";
+			fdt = "fdt@0";
+			ramdisk = "ramdisk@0";
+			signature@0 {
+				algo = "sha256,rsa2048";
+				key-name-hint = "dev";
+				sign-images = "kernel", "fdt", "ramdisk";
+			};
+		};
+	};
+};
+---------------------------------------->8----------------------------------------
+
+You need to change the three '/incbin/' lines, depending on the location of
+your kernel image, device tree blob, and init ramdisk.  The "load" and "entry"
+properties also need to be adjusted if you want to change the physical placement
+of the kernel.
+
+The "key-name-hint" must specify the key name you have created in the step 1.
+
+The FIT file name is arbitrary.  Let's say you saved it into "fit.its".
+
+3. Compile U-Boot with FIT and signature enabled
+
+To use the Verified Boot, you need to enable the following two options:
+  CONFIG_FIT
+  CONFIG_FIT_SIGNATURE
+
+They are disabled by default for UniPhier defconfig files.  So, you need to
+tweak the configuration from "make menuconfig" or friends.
+
+  $ make uniphier_v8_defconfig
+  $ make menuconfig
+      [ enable CONFIG_FIT and CONFIG_FIT_SIGNATURE ]
+  $ make CROSS_COMPILE=aarch64-linux-gnu-
+
+4. Build the image tree blob
+
+After building U-Boot, you will see tools/mkimage.  With this tool, you can
+create an image tree blob as follows:
+
+  $ tools/mkimage -f fit.its -k keys -K dts/dt.dtb -r -F fitImage
+
+The -k option must specify the key directory you have created in step 1.
+
+A file "fitImage" will be created.  This includes kernel, DTB, Init-ramdisk,
+hash data for each of the three, and signature data.
+
+The public key needed for the run-time verification is stored in "dts/dt.dtb".
+
+5. Compile U-Boot again
+
+Since the "dt.dtb" has been updated in step 4, you need to re-compile the
+U-Boot.
+
+  $ make CROSS_COMPILE=aarch64-linux-gnu-
+
+The re-compiled "u-boot.bin" is appended with DTB that contains the public key.
+
+6. Flash the image
+
+Flash the "fitImage" to a storage device (NAND, eMMC, or whatever) on your
+board.
+
+Please note the "u-boot.bin" must be signed, and verified by someone when it is
+loaded.  For ARMv8 SoCs, the "someone" is generally ARM Trusted Firmware BL2.
+ARM Trusted Firmware supports an image authentication mechanism called Trusted
+Board Boot (TBB).  The verification process must be chained from the moment of
+the system reset.  If the Chain of Trust has a breakage somewhere, the verified
+boot process is entirely pointless.
+
+7. Boot verified kernel
+
+Load the fitImage to memory and run the following from the U-Boot command line.
+
+  > bootm <addr>
+
+Here, <addr> is the base address of the fitImage.
+
+If it is successful, you will see messages like follows:
