This change adds necessary xHCI host controller stack layer. This stack will eventually interact with SoC specific USB 3.0 controller drivers to enable USB 3.0 support on different boards.
Based on 'master' branch of u-boot-usb tree.
The series also includes patches to support xHCI on exynos5250, including required driver, device tree changes and a temporary config change to test things finally on smdk5250.

I have done similar work for the DWC and xHCI back port. We seem to have two different implementations.
See my V3 patch series. If you want the initial patch sets or v2 let me know. http://patchwork.ozlabs.org/patch/256451/ http://patchwork.ozlabs.org/patch/256449/ 3/7 is waiting approval http://patchwork.ozlabs.org/patch/256452/ http://patchwork.ozlabs.org/patch/256450/ 6/7 is waiting approval http://patchwork.ozlabs.org/patch/256453/

Please let us know which xHCI/DWC implementation you would like to have in main line.
