The Hardkernel's Odroid XU board was first design with big.LITTLE SoC from Samsung: the Exynos5410. Comparing the board to more popular now Odroid XU3, the differences are: 1. Exynos5410 instead of 5422, 2. MIPI DSI LCD connector, 3. Main PMIC: Maxim 77802 instead of S2MPS11, 4. USB3503+LAN9730 instead of integrated LAN9514, 5. eMMC 4.5 instead of eMMC 5.0, This patch adds initial support for the XU board with working basic functions, eMMC/SD and USB (including attached ethernet adapter).
