+Description
+===========
+
+HiKey is one of 96boards. Hisilicon Kirin6220 processor is installed on HiKey.
+
+More information are listed in `link`_.
+
+How to build
+============
+
+Code Locations

+
+Build Procedure
+---------------
+
+-  Fetch all the above repositories into local host.
+   Make all the repositories in the same ${BUILD\_PATH}.
+
+-  Create the symbol link to OpenPlatformPkg in edk2.
+
+   .. code:: shell
+
+       $cd ${BUILD_PATH}/edk2
+       $ln -sf ../OpenPlatformPkg
+
+-  Prepare AARCH64 && AARCH32 toolchain. Prepare python.
+
+-  If your hikey hardware is built by CircuitCo, update *uefi-tools/platform.config* first. *(optional)*
+   **Uncomment the below sentence. Otherwise, UEFI can't output messages on serial
+   console on hikey.**
+
+   .. code:: shell
+
+       BUILDFLAGS=-DSERIAL_BASE=0xF8015000
+
+   If your hikey hardware is built by LeMarker, nothing to do.
+
+-  Build it as debug mode. Create your own build script file or you could refer to **build\_uefi.sh** in l-loader git repository.
+
+   .. code:: shell
+
+       BUILD_OPTION=DEBUG
+       export AARCH64_TOOLCHAIN=GCC5
+       export UEFI_TOOLS_DIR=${BUILD_PATH}/uefi-tools
+       export EDK2_DIR=${BUILD_PATH}/edk2
+       EDK2_OUTPUT_DIR=${EDK2_DIR}/Build/HiKey/${BUILD_OPTION}_${AARCH64_TOOLCHAIN}
+       # Build fastboot for ARM Trust Firmware. It's used for recovery mode.
+       cd ${BUILD_PATH}/atf-fastboot
+       CROSS_COMPILE=aarch64-linux-gnu- make PLAT=hikey DEBUG=1
+       # Convert DEBUG/RELEASE to debug/release
+       FASTBOOT_BUILD_OPTION=$(echo ${BUILD_OPTION} | tr '[A-Z]' '[a-z]')
+       cd ${EDK2_DIR}
+       # Build UEFI & ARM Trust Firmware
+       ${UEFI_TOOLS_DIR}/uefi-build.sh -b ${BUILD_OPTION} -a ../arm-trusted-firmware hikey
+       # Generate l-loader.bin
+       cd ${BUILD_PATH}/l-loader
+       ln -sf ${EDK2_OUTPUT_DIR}/FV/bl1.bin
+       ln -sf ${EDK2_OUTPUT_DIR}/FV/fip.bin
+       ln -sf ${BUILD_PATH}/atf-fastboot/build/hikey/${FASTBOOT_BUILD_OPTION}/bl1.bin fastboot.bin
+       python gen_loader.py -o l-loader.bin --img_bl1=bl1.bin --img_ns_bl1u=BL33_AP_UEFI.fd
+       arm-linux-gnueabihf-gcc -c -o start.o start.S
+       arm-linux-gnueabihf-ld -Bstatic -Tl-loader.lds -Ttext 0xf9800800 start.o -o loader
+       arm-linux-gnueabihf-objcopy -O binary loader temp
+       python gen_loader_hikey.py -o l-loader.bin --img_loader=temp --img_bl1=bl1.bin --img_ns_bl1u=fastboot.bin
+
+-  Generate partition table for aosp. The eMMC capacity is either 4GB or 8GB. Just change "aosp-4g" to "linux-4g" for debian.
+
+   .. code:: shell
+
+       $PTABLE=aosp-4g SECTOR_SIZE=512 bash -x generate_ptable.sh
+
+Setup Console
+-------------
+
+-  Install ser2net. Use telnet as the console since UEFI fails to display Boot Manager GUI in minicom. **If you don't need Boot Manager GUI, just ignore this section.**
+
+   .. code:: shell
+
+       $sudo apt-get install ser2net
+
+-  Configure ser2net.
+
+   .. code:: shell
+
+       $sudo vi /etc/ser2net.conf
+
+   Append one line for serial-over-USB in below.
+   *#ser2net.conf*
+
+   .. code:: shell
+
+       2004:telnet:0:/dev/ttyUSB0:115200 8DATABITS NONE 1STOPBIT banner
+
+-  Open the console.
+
+   .. code:: shell
+
+       $telnet localhost 2004
+
+   And you could open the console remotely, too.
+
+Flush images in recovery mode
+-----------------------------
+
+-  Make sure Pin3-Pin4 on J15 are connected for recovery mode. Then power on HiKey.
+
+-  Remove the modemmanager package. This package may cause the idt tool failure.
+
+   .. code:: shell
+
+       $sudo apt-get purge modemmanager
+
+-  Run the command to download l-loader.bin into HiKey.
+
+   .. code:: shell
+
+       $sudo python hisi-idt.py -d /dev/ttyUSB1 --img1 l-loader.bin
+
+-  Update images. All aosp or debian images could be fetched from `link <https://builds.96boards.org/>`__.
+
+   .. code:: shell
+
+       $sudo fastboot flash ptable prm_ptable.img
+       $sudo fastboot flash fastboot 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
+
+Boot UEFI in normal mode
+------------------------
+
+-  Make sure Pin3-Pin4 on J15 are open for normal boot mode. Then power on HiKey.
+
