This adds platform code for the Libre Computer CC "Le Potato" board based on a Meson GXL (S905X) SoC with the Meson GXL configuration. This initial submission supports UART, MMC/SDCard and Ethernet with the Internal RMII PHY. The meson-gxl-s905x-libretech-cc.dts is synchronised from the linux 4.13 stable tree as of 4.13.8.

U-Boot for LibreTech CC ======================= LibreTech CC is a single board computer manufactured by Libre Technology with the following specifications: - Amlogic S905X ARM Cortex-A53 quad-core SoC @ 2GHz - ARM Mali 450 GPU - 2GB DDR3 SDRAM - Gigabit Ethernet - HDMI 2.0 4K/60Hz display - 40-pin GPIO header - 4 x USB 2.0 Host, 1 x USB OTG - eMMC, microSD - Infrared receiver Schematics are available on the manufacturer website. Currently the U-Boot port supports the following devices: - serial - eMMC, microSD - Ethernet U-Boot compilation ================== > export ARCH=arm > export CROSS_COMPILE=aarch64-none-elf- > make libretech-cc_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/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:$PATH > git clone https://github.com/BayLibre/u-boot.git -b libretech-cc amlogic-u-boot > cd amlogic-u-boot > make libretech_cc_defconfig > make > export FIPDIR=$PWD/fip Go back to mainline U-Boot source tree then : > 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 > $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 > $FIPDIR/gxl/aml_encrypt_gxl --bootmk \ --output fip/u-boot.bin \ --bl2 fip/bl2.n.bin.sig \ --bl30 fip/bl30_new.bin.enc \ --bl31 fip/bl31.img.enc \ --bl33 fip/bl33.bin.enc and then write the image to SD with: > DEV=/dev/your_sd_device > dd if=fip/u-boot.bin.sd.bin of=$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
