+HiKey960
+========
+
+HiKey960 is one of 96boards. Hisilicon Hi3660 processor is installed on HiKey960.
+
+More information are listed in `link`_.
+
+How to build
+------------
+
+Code Locations
+~~~~~~~~~~~~~~
+
+- Trusted Firmware-A:
+ `link <https://github.com/ARM-software/arm-trusted-firmware>`__
+
+- OP-TEE:
+ `link <https://github.com/OP-TEE/optee_os>`__
+
+- edk2:
+ `link <https://github.com/96boards-hikey/edk2/tree/testing/hikey960_v2.5>`__
+
+- OpenPlatformPkg:
+ `link <https://github.com/96boards-hikey/OpenPlatformPkg/tree/testing/hikey960_v1.3.4>`__
+
+- l-loader:
+ `link <https://github.com/96boards-hikey/l-loader/tree/testing/hikey960_v1.2>`__
+
+Build Procedure
+~~~~~~~~~~~~~~~
+
+- Fetch all the above 5 repositories into local host.
+ Make all the repositories in the same ${BUILD\_PATH}.
+
+ .. code:: shell
+
+ git clone https://github.com/ARM-software/arm-trusted-firmware -b integration
+ git clone https://github.com/OP-TEE/optee_os
+ git clone https://github.com/96boards-hikey/edk2 -b testing/hikey960_v2.5
+ git clone https://github.com/96boards-hikey/OpenPlatformPkg -b testing/hikey960_v1.3.4
+ git clone https://github.com/96boards-hikey/l-loader -b testing/hikey960_v1.2
+
+- Create the symbol link to OpenPlatformPkg in edk2.
+
+ .. code:: shell
+
+ $cd ${BUILD_PATH}/edk2
+ $ln -sf ../OpenPlatformPkg
+
+- Prepare AARCH64 toolchain.
+
+- If your hikey960 hardware is v1, update *OpenPlatformPkg/Platforms/Hisilicon/HiKey960/HiKey960.dsc* first. *(optional)*
+
+ .. code:: shell
+
+ DEFINE SERIAL_BASE=0xFDF05000
+
+ If your hikey960 hardware is v2 or newer, nothing to do.
+
+- Build it as debug mode. Create script file for build.
+
+ .. code:: shell
+
+ cd {BUILD_PATH}/arm-trusted-firmware
+ sh ../l-loader/build_uefi.sh hikey960
+
+- Generate l-loader.bin and partition table.
+ *Make sure that you're using the sgdisk in the l-loader directory.*
+
+ .. code:: shell
+
+ cd ${BUILD_PATH}/l-loader
+ ln -sf ${EDK2_OUTPUT_DIR}/FV/bl1.bin
+ ln -sf ${EDK2_OUTPUT_DIR}/FV/bl2.bin
+ ln -sf ${EDK2_OUTPUT_DIR}/FV/fip.bin
+ ln -sf ${EDK2_OUTPUT_DIR}/FV/BL33_AP_UEFI.fd
+ make hikey960
+
+Setup Console
+-------------
+
+- Install ser2net. Use telnet as the console since UEFI will output window
+ that fails to display in minicom.
+
+ .. code:: shell
+
+ $sudo apt-get install ser2net
+
+- Configure ser2net.
+
+ .. code:: shell
+
+ $sudo vi /etc/ser2net.conf
+
+ Append one line for serial-over-USB in *#ser2net.conf*
+
+ ::
+
+ 2004:telnet:0:/dev/ttyUSB0:115200 8DATABITS NONE 1STOPBIT banner
+
+- Start ser2net
+
+ .. code:: shell
+
+ $sudo killall ser2net
+ $sudo ser2net -u
+
+- Open the console.
+
+ .. code:: shell
+
+ $telnet localhost 2004
+
+ And you could open the console remotely, too.
+
+Boot UEFI in recovery mode
+--------------------------
+
+- Fetch that are used in recovery mode. The code location is in below.
+ `link <https://github.com/96boards-hikey/tools-images-hikey960>`__
+
+- Prepare recovery binary.
+
+ .. code:: shell
+
+ $cd tools-images-hikey960
+ $ln -sf ${BUILD_PATH}/l-loader/l-loader.bin
+ $ln -sf ${BUILD_PATH}/l-loader/fip.bin
+ $ln -sf ${BUILD_PATH}/l-loader/recovery.bin
+
+- Prepare config file.
+
+ .. code:: shell
+
+ $vi config
+ # The content of config file
+ ./sec_usb_xloader.img 0x00020000
+ ./sec_uce_boot.img 0x6A908000
+ ./recovery.bin 0x1AC00000
+
+- Remove the modemmanager package. This package may causes hikey\_idt tool failure.
+
+ .. code:: shell
+
+ $sudo apt-get purge modemmanager
+
+- Run the command to download recovery.bin into HiKey960.
+
+ .. code:: shell
+
+ $sudo ./hikey_idt -c config -p /dev/ttyUSB1
+
+- UEFI running in recovery mode.
+ When prompt '.' is displayed on console, press hotkey 'f' in keyboard. Then Android fastboot app is running.
+ The timeout of prompt '.' is 10 seconds.
+
+- Update images.
+
+ .. code:: shell
+
+ $sudo fastboot flash ptable prm_ptable.img
+ $sudo fastboot flash xloader sec_xloader.img
+ $sudo fastboot flash fastboot l-loader.bin
+ $sudo fastboot flash fip fip.bin
+ $sudo fastboot flash boot boot.img
+ $sudo fastboot flash cache cache.img
+ $sudo fastboot flash system system.img
+ $sudo fastboot flash userdata userdata.img
+
+- Notice: UEFI could also boot kernel in recovery mode, but BL31 isn't loaded in
+ recovery mode.
+
+Boot UEFI in normal mode
+------------------------
+
+- Make sure "Boot Mode" switch is OFF for normal boot mode. Then power on HiKey960.
