Probably this patch should had been an RFC? or you should mention about these in the commit message to understand why are there. Best regards,

Actually I was quite surprised that board worked fine with this basic setup.

The Hardkernel's Odroid XU board was first design with big.LITTLE SoC from Samsung: the Exynos5410. Comparing now to more popular Odroid XU3 the differences are: 1. Exynos5410 instead of 5422, 2. DisplayPort, 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).
