arm: Add LibreTech CC support based on Meson GXL family 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 compilation
==================

> 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 \

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 \

--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
