+U-Boot for LibreTech CC
+=======================
+
+LibreTech CC is a single board computer manufactured by Libre Technology

+
+ - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 1.5GHz
+ - ARM Mali 450 GPU

+
+.. code-block:: bash
+
+ $ export CROSS_COMPILE=aarch64-none-elf-
+ $ make libretech-cc_defconfig
+ $ make
+
+Image creation
+--------------
+
+To boot the system, u-boot must be combined with several earlier stage
+bootloaders:
+
+* bl2.bin: vendor-provided binary blob
+* bl21.bin: built from vendor u-boot source
+* bl30.bin: vendor-provided binary blob
+* bl301.bin: built from vendor u-boot source
+* bl31.bin: vendor-provided binary blob
+* acs.bin: built from vendor u-boot source
+
+These binaries and the tools required below have been collected and prebuilt
+for convenience at <https://github.com/BayLibre/u-boot/releases/>
+
+Download and extract the libretech-cc release from there, and set FIPDIR to
+point to the `fip` subdirectory.
+
+.. code-block:: bash
+
+ $ export FIPDIR=/path/to/extracted/fip
+
+Alternatively, you can obtain the original vendor u-boot tree which
+contains the required blobs and sources, and build yourself.
+Note that old compilers are required for this to build. The compilers here
+are suggested by Amlogic, and they are 32-bit x86 binaries.
+
+.. 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

+ $ cd amlogic-u-boot
+ $ make libretech_cc_defconfig
+ $ make
+ $ export FIPDIR=$PWD/fip
+
+Once you have the binaries available (either through the prebuilt download,
+or having built the vendor u-boot yourself), you can then proceed to glue
+everything together. 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/

+ 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

+ --bl30 fip/bl30_new.bin.enc \
+ --bl31 fip/bl31.img.enc \
+ --bl33 fip/bl33.bin.enc
+
+and 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
+
+Note that Amlogic provides aml_encrypt_gxl as a 32-bit x86 binary with no
+source code. Should you prefer to avoid that, there are open source reverse
+engineered versions available:
+
+1. gxlimg <https://github.com/repk/gxlimg>, which comes with a handy
+ Makefile that automates the whole process.
+2. meson-tools <https://github.com/afaerber/meson-tools>
+
+However, these community-developed alternatives are not endorsed by or
+supported by Amlogic.

+U-Boot for ODROID-N2
+====================
+
+ODROID-N2 is a single board computer manufactured by Hardkernel
+Co. Ltd with the following specifications:
+
+ - Amlogic S922X ARM Cortex-A53 dual-core + Cortex-A73 quad-core SoC
+ - 4GB DDR4 SDRAM
+ - Gigabit Ethernet
+ - HDMI 2.1 4K/60Hz display
+ - 40-pin GPIO header
+ - 4 x USB 3.0 Host, 1 x USB OTG
+ - eMMC, microSD
+ - Infrared receiver
+
+Schematics are available on the manufacturer website.

+Image creation
+--------------
+
+Amlogic doesn't provide sources for the firmware and for tools needed
+to create the bootloader image, so it is necessary to obtain them from
+the git tree published by the board vendor:
