+Synopsys VDK Software Development Platform
+
+Intro
+=====
+
+The Virtualizer Development Kit (VDK) Family for ARM Cortex Products
+consists of a set of virtual prototypes that provide a virtualizer for 
+the ARM core variants. The VDK is a standalone package that runs on an 
+host computer.
+
+Buildroot will generate the kernel image and a minimal root filesystem.
+
+How to build it
+===============
+
+Configure Buildroot
+-------------------
+
+Configuring Buildroot is pretty simple, just execute:
+
+  $ make snps_aarch64_vdk_defconfig
+
+Build the rootfs and kernel
+---------------------------
+
+Note: you will need to have access to the network, since Buildroot will
+download the packages' sources.
+
+You may now build your rootfs with:
+
+  $ make
+
+(This may take a while)
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:
+
+    output/images/
+    -- rootfs.ext2
+    -- Image
+
+Installing your rootfs and Image
+================================
+Now copy the content of the output/images folder to the VDK' skins folder:
+
+   $ cp rootfs.ext2 Image <vdk_installation_path>/skins/Vanilla-Cortex/ARMv8
+
+
+Starting the VDK
+================================
+Go the VDK' installation root and execute the 'start' script:
+
+   $ cd <vdk_installation_path>
+   $ ./start.sh
+
+The VP Explorer application will be executed, starting the simulation
+automatically.
+
+For more information about Synopsys' VDK please check:
+http://www.synopsys.com/Prototyping/VirtualPrototyping/Pages/default.aspx

 This is redundant.

 We now have BR2_LINUX_KERNEL_IMAGE which replaces the above two configs. And
it's even the default for aarch64, so you can just leave these two out.

 Arnout
