 HiKey board
 ###########

 Introduction
 ============

 HiKey is the first certified 96Boards Consumer Edition board. The board/SoC has:

 * HiSilicon Kirin 6220 eight-core ARM Cortex-A53 64-bit SoC running at 1.2GHz.
 * ARM Mali 450-MP4 GPU
 * 1GB 800MHz LPDDR3 DRAM
 * 4GB eMMC Flash Storage
 * microSD
 * 802.11a/b/g/n WiFi, Bluetooth

 The HiKey schematic can be found here:
 https://github.com/96boards/documentation/blob/master/consumer/hikey/hikey620/hardware-docs/HiKey_schematics_LeMaker_version_Rev_A1.pdf

 The SoC datasheet can be found here:
 https://github.com/96boards/documentation/blob/master/consumer/hikey/hikey620/hardware-docs/Hi6220V100_Multi-Mode_Application_Processor_Function_Description.pdf

 Currently the u-boot port supports:

 * USB
 * eMMC
 * SD card
 * GPIO

 The HiKey U-Boot port has been tested with l-loader, booting ATF, which then
 boots U-Boot as the bl33.bin executable.

 Compile from source
 ===================

 First get all the sources

 .. code-block:: bash

   mkdir -p ~/hikey/src ~/hikey/bin
   cd ~/hikey/src
   git clone https://github.com/96boards-hikey/edk2 -b testing/hikey960_v2.5
   git clone https://github.com/TrustedFirmware-A/trusted-firmware-a
   git clone https://github.com/96boards-hikey/l-loader -b testing/hikey960_v1.2
   git clone https://github.com/96boards-hikey/OpenPlatformPkg -b testing/hikey960_v1.3.4
   git clone https://github.com/96boards-hikey/atf-fastboot
   wget https://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey/release/hisi-idt.py

 Get the BL30 mcuimage.bin binary. It is shipped as part of the UEFI source.
 The latest version can be obtained from the OpenPlatformPkg repo.

 .. code-block:: bash

   cp OpenPlatformPkg/Platforms/Hisilicon/HiKey/Binary/mcuimage.bin ~/hikey/bin/

 Get nvme.img binary

 .. code-block:: bash

   wget -P ~/hikey/bin https://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey/release/nvme.img

 Compile U-Boot
 ==============

 .. code-block:: bash

   cd ~/hikey/src/u-boot
   make CROSS_COMPILE=aarch64-linux-gnu- hikey_config
   make CROSS_COMPILE=aarch64-linux-gnu-
   cp u-boot.bin ~/hikey/bin

 Compile ARM Trusted Firmware (ATF)
 ==================================

 .. code-block:: bash

   cd ~/hikey/src/trusted-firmware-a
   make CROSS_COMPILE=aarch64-linux-gnu- all fip \
     SCP_BL2=~/hikey/bin/mcuimage.bin \
     BL33=~/hikey/bin/u-boot.bin DEBUG=1 PLAT=hikey

 Copy the resulting FIP binary

 .. code-block:: bash

   cp build/hikey/debug/fip.bin ~/hikey/bin

 Compile ATF Fastboot
 ====================

 .. code-block:: bash

   cd ~/hikey/src/atf-fastboot
   make CROSS_COMPILE=aarch64-linux-gnu- PLAT=hikey DEBUG=1

 Compile l-loader
 ================

 .. code-block:: bash

   cd ~/hikey/src/l-loader
   ln -sf ~/hikey/src/trusted-firmware-a/build/hikey/debug/bl1.bin
   ln -sf ~/hikey/src/trusted-firmware-a/build/hikey/debug/bl2.bin
   ln -sf ~/hikey/src/atf-fastboot/build/hikey/debug/bl1.bin fastboot.bin
   make hikey PTABLE_LST=aosp-8g

 Copy the resulting binaries

 .. code-block:: bash

   cp *.img ~/hikey/bin
   cp l-loader.bin ~/hikey/bin
   cp recovery.bin ~/hikey/bin

 These instructions are adapted from
 https://github.com/TrustedFirmware-A/trusted-firmware-a/blob/master/docs/plat/hikey.rst

 Flashing
 ========

 1. Connect the second jumper on J15 BOOT SEL, to go into recovery mode and flash l-loader.bin with
 the hisi-idt.py utility. Then connect a USB A to B mini cable from your PC to the USB OTG port of HiKey and execute the below command.

 The command below assumes HiKey enumerated as the first USB serial port

 .. code-block:: bash

   sudo python ~/hikey/src/hisi-idt.py -d /dev/ttyUSB0 --img1 ~/hikey/bin/recovery.bin

 2. Once LED 0 comes on solid, HiKey board should be detected as a fastboot device.

 .. code-block::

   sudo fastboot devices

   0123456789ABCDEF	fastboot

 3. Flash the images

 .. code-block::

   sudo fastboot flash ptable ~/hikey/bin/prm_ptable.img
   sudo fastboot flash loader ~/hikey/bin/l-loader.bin
   sudo fastboot flash fastboot ~/hikey/bin/fip.bin
   sudo fastboot flash nvme ~/hikey/bin/nvme.img

 4. Disconnect second jumper on J15 BOOT SEL, and reset the board and you will now (hopefully)
    have ATF, booting u-boot from eMMC.

    Note: To get USB host working, also disconnect the USB OTG cable used for flashing. Otherwise you
    will get 'dwc_otg_core_host_init: Timeout!' errors.

	1. Connect the second jumper on J15 BOOT SEL, to go into recovery mode and flash l-loader.bin with
	the hisi-idt.py utility. Then connect a USB A to B mini cable from your PC to the USB OTG port of HiKey and execute the below command.

	The command below assumes HiKey enumerated as the first USB serial port

	.. code-block:: bash

	sudo python ~/hikey/src/hisi-idt.py -d /dev/ttyUSB0 --img1 ~/hikey/bin/recovery.bin

	2. Once LED 0 comes on solid, HiKey board should be detected as a fastboot device.

	.. code-block::

	sudo fastboot devices

	0123456789ABCDEF fastboot

	3. Flash the images

	.. code-block::

	sudo fastboot flash ptable ~/hikey/bin/prm_ptable.img
	sudo fastboot flash loader ~/hikey/bin/l-loader.bin
	sudo fastboot flash fastboot ~/hikey/bin/fip.bin
	sudo fastboot flash nvme ~/hikey/bin/nvme.img

	4. Disconnect second jumper on J15 BOOT SEL, and reset the board and you will now (hopefully)
	have ATF, booting u-boot from eMMC.

	Note: To get USB host working, also disconnect the USB OTG cable used for flashing. Otherwise you
	will get 'dwc_otg_core_host_init: Timeout!' errors.
