+Description
+===========
+
+Versatile Express (VE) family development platform provides an
+ultra fast environment for prototyping arm-v7 System-on-Chip designs.
+VE Fixed Virtual Platforms (FVP) are simulations of Versatile Express boards.
+The platform in arm-trusted-firmware has been verified with Arm Cortex-A5
+and Cortex-A7 VE FVP's. This platform is tested on and only expected to work
+with single core models.
+
+Boot Sequence
+=============
+
+BL1 --> BL2 --> BL32(sp_min) --> BL33(u-boot) --> Linux kernel
+
+How to build
+============
+
+Code Locations
+---------------
+- `U-boot <https://git.linaro.org/landing-teams/working/arm/u-boot.git>`__
+
+- `arm-trusted-firmware <https://github.com/ARM-software/arm-trusted-firmware>`__
+
+Build Procedure
+---------------
+
+- Obtain arm toolchain. The software stack has been verified with linaro 6.2
+ `arm-linux-gnueabihf <https://releases.linaro.org/components/toolchain/binaries/6.2-2016.11/arm-linux-gnueabihf/>`__.
+ Set the CROSS_COMPILE environment variable to point to the toolchain folder.
+
+- Fetch and build u-boot.
+ Make the .config file using the command:
+
+ .. code:: shell
+
+ make ARCH=arm vexpress_aemv8a_aarch32_config
+
+ Make the u-boot binary for Cortex-A5 using the command:
+
+ .. code:: shell
+
+ make ARCH=arm SUPPORT_ARCH_TIMER=no
+
+ Make the u-boot binary for Cortex-A7 using the command:
+
+ .. code:: shell
+
+ make ARCH=arm
+
+
+- Build TF-A:
+
+ The make command for Cortex-A5 is:
+
+ .. code:: shell
+
+ make PLAT=fvp_ve ARCH=aarch32 ARM_ARCH_MAJOR=7 ARM_CORTEX_A5=yes \
+ AARCH32_SP=sp_min FVP_HW_CONFIG_DTS=fdts/fvp-ve-Cortex-A5x1.dts \
+ ARM_XLAT_TABLES_LIB_V1=1 BL33=<path_to_u-boot.bin> all fip
+
+ The make command for Cortex-A7 is:
+
+ .. code:: shell
+
+ make PLAT=fvp_ve ARCH=aarch32 ARM_ARCH_MAJOR=7 ARM_CORTEX_A7=yes \
+ AARCH32_SP=sp_min FVP_HW_CONFIG_DTS=fdts/fvp-ve-Cortex-A7x1.dts \
+ BL33=<path_to_u-boot.bin> all fip
+
+Run Procedure
+-------------
+
+The following model parameters should be used to boot Linux using the build of
+arm-trusted-firmware-a made using the above make commands:
+
+ .. code:: shell
+
+ ./<path_to_model> <path_to_bl1.elf> \
+ -C motherboard.flashloader1.fname=<path_to_fip.bin> \
+ --data cluster.cpu0=<path_to_zImage>@0x80080000 \
+ --data cluster.cpu0=<path_to_ramdisk>@0x84000000
