+U-Boot for ODROID-C4
+====================
+
+ODROID-C4 is a single board computer manufactured by Hardkernel
+Co. Ltd with the following specifications:
+
+ - Amlogic S905X3 ARM Cortex-A55 quad-core SoC
+ - 4GiB DDR4 SDRAM
+ - Gigabit Ethernet (External Realtek RTL8211F PHY)
+ - 4 x USB 3.0 Host ports
+ - 1 x USB 2.0 OTG port
+ - HDMI 2.0
+ - eMMC
+ - SDcard
+ - 40-pin GPIO header
+ - Infrared receiver
+
+Currently the u-boot port supports the following devices:
+ - Serial
+ - Clock controller
+ - USB
+
+u-boot compilation
+==================
+
+ export ARCH=arm
+ export CROSS_COMPILE=aarch64-none-elf-
+ make odroid-c4_defconfig
+ make
+
+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:
+
+ 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/14.04/components/toolchain/binaries/gcc-linaro-arm-none-eabi-4.8-2014.04_linux.tar.xz
+ tar xf gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.xz
+ tar xf gcc-linaro-arm-none-eabi-4.8-2014.04_linux.tar.xz
+ export PATH=$PWD/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux/bin:$PWD/gcc-linaro-arm-none-eabi-4.8-2014.04_linux/bin:$PATH
+ git clone --depth 1 https://github.com/hardkernel/u-boot.git -b odroidg12-v2015.01 hardkernel-u-boot
+ cd hardkernel-u-boot
+ make odroidc4_defconfig
+ make
+ export UBOOTDIR=$PWD
+
+Go back to mainline U-Boot source tree and then:
+
+ mkdir fip
+ $UBOOTDIR/fip/g12a/aml_encrypt_g12a --bl30sig --level v3 \
+ --input $UBOOTDIR/build/fip/bl30_new.bin \
+ --output fip/bl30_new.bin.g12.enc
+ $UBOOTDIR/fip/g12a/aml_encrypt_g12a --bl3sig --type bl30 --level v3 \
+ --input fip/bl30_new.bin.g12.enc \
+ --output fip/bl30_new.bin.enc
+ $UBOOTDIR/fip/g12a/aml_encrypt_g12a --bl3sig --type bl31 --level v3 \
+ --input $UBOOTDIR/fip/g12a/bl31.img \
+ --output fip/bl31.img.enc
+ $UBOOTDIR/fip/g12a/aml_encrypt_g12a --bl3sig --type bl33 --level v3 \
+ --compress lz4 \
+ --input u-boot.bin \
+ --output fip/bl33.bin.enc
+ $UBOOTDIR/fip/g12a/aml_encrypt_g12a --bl2sig \
+ --input $UBOOTDIR/build/fip/bl2_new.bin \
+ --output fip/bl2.n.bin.sig
+ $UBOOTDIR/fip/g12a/aml_encrypt_g12a --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 \
+ --ddrfw1 $UBOOTDIR/fip/g12a/ddr4_1d.fw \
+ --ddrfw2 $UBOOTDIR/fip/g12a/ddr4_2d.fw \
+ --ddrfw4 $UBOOTDIR/fip/g12a/piei.fw \
+ --ddrfw8 $UBOOTDIR/fip/g12a/aml_ddr.fw \
+ --level v3
+
+and then write the image to SD with:
+
+ DEV=/dev/your_sd_device
+ dd if=fip/u-boot.bin of=$DEV conv=fsync,notrunc bs=512 seek=1
