+U-Boot for WeTek Core2
+======================
+
+WeTek Core2 is an Android STB based on the Q200 reference design with
+the following specifications:
+
+ - Amlogic S912 ARM Cortex-A53 octo-core SoC @ 1.5GHz
+ - ARM Mali T820 GPU
+ - 3GB DDR4 SDRAM
+ - 10/100 Realtek RTL8152 Ethernet (internal USB)
+ - HDMI 2.0 4K/60Hz display
+ - 2x USB 2.0 Host, 1x USB 2.0 OTG (internal)
+ - 32GB eMMC
+ - microSD
+ - SDIO Wifi Module, Bluetooth
+ - Two channel IR receiver
+
+U-Boot compilation
+------------------
+
+.. code-block:: bash
+
+ $ export CROSS_COMPILE=aarch64-none-elf-
+ $ make wetek-core2_defconfig
+ $ make
+
+Image creation
+--------------
+
+Amlogic does not provide sources for the firmware or the tools needed
+to create the bootloader image, and WeTek has not publicly shared the
+precompiled FIP binaries. However the public Khadas VIM2 sources also
+work with the Core2 box so we can use the Khadas git tree:
+
+.. code-block:: bash
+
+ $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
+ $ wget https://releases.linaro.org/archive/13.11/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
+ $ tar xvfJ gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
+ $ tar xvfJ gcc-linaro-arm-none-eabi-4.8-2013.11_linux.tar.xz
+ $ export PATH=$PWD/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux/bin:$PWD/gcc-linaro-arm-none-eabi-4.8-2013.11_linux/bin:$PATH
+ $ git clone https://github.com/khadas/u-boot -b khadas-vim-v2015.01 vim-u-boot
+ $ cd vim-u-boot
+ $ make kvim2_defconfig
+ $ make
+ $ export FIPDIR=$PWD/fip
+
+Go back to mainline U-Boot source tree then:
+
+.. code-block:: bash
+
+ $ mkdir fip
+ $ cp $FIPDIR/gxl/bl2.bin fip/
+ $ cp $FIPDIR/gxl/acs.bin fip/
+ $ cp $FIPDIR/gxl/bl21.bin fip/
+ $ cp $FIPDIR/gxl/bl30.bin fip/
+ $ cp $FIPDIR/gxl/bl301.bin fip/
+ $ cp $FIPDIR/gxl/bl31.img fip/
+ $ cp u-boot.bin fip/bl33.bin
+ $ $FIPDIR/blx_fix.sh \
+ fip/bl30.bin \
+ fip/zero_tmp \
+ fip/bl30_zero.bin \
+ fip/bl301.bin \
+ fip/bl301_zero.bin \
+ fip/bl30_new.bin \
+ bl30
+ $ python $FIPDIR/acs_tool.pyc fip/bl2.bin fip/bl2_acs.bin fip/acs.bin 0
+ $ $FIPDIR/blx_fix.sh \
+ fip/bl2_acs.bin \
+ fip/zero_tmp \
+ fip/bl2_zero.bin \
+ fip/bl21.bin \
+ fip/bl21_zero.bin \
+ fip/bl2_new.bin \
+ bl2
+ $ $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl30_new.bin
+ $ $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl31.img
+ $ $FIPDIR/gxl/aml_encrypt_gxl --bl3enc --input fip/bl33.bin
+ $ $FIPDIR/gxl/aml_encrypt_gxl --bl2sig --input fip/bl2_new.bin --output fip/bl2.n.bin.sig
+ $ $FIPDIR/gxl/aml_encrypt_gxl --bootmk \
+ --output fip/u-boot.bin \
+ --bl2 fip/bl2.n.bin.sig \
+ --bl30 fip/bl30_new.bin.enc \
+ --bl31 fip/bl31.img.enc \
+ --bl33 fip/bl33.bin.enc
+
+then write the image to SD with:
+
+.. code-block:: bash
+
+ $ DEV=/dev/your_sd_device
+ $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1
+ $ dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444
