Sat Feb 3 11:02:02 UTC 2018
This patch provides support for the board Odroid XU4
This version is using the latest 4.9 kernel released by Hardkernel,
and the current u-boot 2017.05 also from Hardkernel.
The support was implemented based on comments about Andi's patch (https://patchwork.ozlabs.org/patch/640695/).

+Odroid XU-4 board with Samsung Exynos 5422 SoC
+
+Introduction
+------------
+
+The Odroid XU 4 board is developed and shipped by Hrdkernel (hardkernel.com). It
+uses the Samsung Exynos 5422 Soc.
+
+Odroid boot process
+-------------------
+
+The odroid boot process requires three stages of boot plus trust zone:
+
+ boot level 1
+
+ |
+ V
+
+ boot level 2
+
+ |
+ V
+
+ u-boot
+
+and they need to be raw copied to the SD card in the following order:
+
+ +----------------+----------------+
+ | boot level 1 | 1 block |
+ +----------------+----------------+
+ | boot level 2 | 31 block |
+ +----------------+----------------+
+ | u-boot | 63 block |
+ +----------------+----------------+
+ | trust zone | 2111 block |
+ +----------------+----------------+
+ | boot partition | 4096 block |
+ +----------------+----------------+
+ | rootfs | |
+ +----------------+----------------+
+
+
+How to build it
+===============
+
+ $ make odroidxu4_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 all output files in output/images/
+
+
+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 ODROID-XU4, and power it up. Your new system
+should come up now.
