+Libre Computer Le Potato (AML-S905X-CC)
+
+Intro
+=====
+
+Libre Computer "Le Potato" is a low cost SBC based around an Amlogic
+s905x SoC (quad A53), 2GB DDR3, Mali-450:
+
+https://libre.computer/products/aml-s905x-cc/
+
+How to build it
+===============
+
+Configure Buildroot:
+
+  $ make lepotato_defconfig
+
+Then you can edit the build options using
+
+  $ make menuconfig
+
+Compile everything and build rootfs image:
+
+  $ make
+
+Note: you will need to have access to the network, since Buildroot
+will download the packages' sources.
+
+Result of the build
+-------------------
+
+After building, you should obtain this tree:
+
+output/images/
++-- amlogic-boot-fip
++   +-- axg.inc
++   +--  build-fip.sh
++   +--  g12a.inc
++   +--  gxbb.inc
++   +--  gxl.inc
++   `-- lepotato
++       +-- acs.bin
++       +-- acs_tool.py
++       +-- aml_encrypt_gxl
++       +-- bl21.bin
++       +-- bl2.bin
++       +-- bl301.bin
++       +-- bl30.bin
++       +-- bl31.img
++       +-- blx_fix.sh
++       `-- Makefile
++-- boot.vfat
++-- extlinux
++   `-- extlinux.conf
++-- fip
++   +--  u-boot.bin
++   +--  u-boot.bin.sd.bin
++   +--  u-boot.bin.usb.bl2
++   `-- u-boot.bin.usb.tpl
++-- Image
++-- meson-gxl-s905x-libretech-cc.dtb
++-- rootfs.ext2
++-- rootfs.ext4 -> rootfs.ext2
++-- rootfs.tar
++-- sdcard.img
+`-- u-boot.bin
+
+The post-image script uses the files in the amlogic-boot-fip folder to sign
+the bootloader image before integrating it into the sdcard image.
+
+How to write the SD card or eMMC
+================================
+
+Once the build process is finished you will have an image called "sdcard.img"
+in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an SD card or eMMC with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+
+Insert the micro SDcard into your Le Potato and power it up. The console
+is on the serial line, 115200 8N1.

Tested-by: Kilian Zinnecker <kilian.zinnecker@mail.de>

Build test only (as I don't have the board), with ./utils/docker-run

Best regards,
Kilian
