This patch adds support for the Libre Computer AML-S905X-CC based
on an Amlogic S905X SoCs.
The board features :
- 4xCortex-A53 Cores
- 1 or 2Gib or DDR4
- RS232 TTL Header
- MicroUSB for Power Only
- HDMI 2.0b output + CEC
- CVBS + Audio Jack
- 10/100 Ethernet
- 4xUSB2.0
- IR Receiver
- SDCard
- eMMC optional slot
- 40pin connector partially RPi compatible
- 8Pin I2S 7.1 connector
- 3Pin SPDIF connector
The board is entirely supported since U-boot 2018.01 and Linux 4.14.
The Buildroot support is done with upstream only package and the
previously submitted "aml-s905x-cc-fip" package to generate a valid
bootable SDCard image.

+Libre Computer AML-S905X-CC
+
+Intro
+=====
+To be able to use AML-S905X-CC board with the images generated by
+Buildroot, you have to prepare the SDCard or eMMC.
+
+How to build it
+===============
+
+ $ make aml-s905-cc_defconfig
+
+Then you can edit the build options using
+
+ $ make menuconfig
+
+Compile all 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/
+ +-- Image
+ +-- boot.vfat
+ +-- meson-gxl-s905x-libretech-cc.dtb
+ +-- rootfs.ext2
+ +-- rootfs.ext4
+ +-- rootfs.tar
+ +-- sdcard.img
+ `-- u-boot.bin
+
+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 SDcard into your AML-S905X-CC, and power it up. Your new system
+should come up now.
