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 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
|
||||

|

|
||||
> 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/

|

|

> $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 \

|
||||
--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
