[U-Boot] [PATCH 0/5] exynos5: usb: Enable USB 2.0 support
This patchset series adds support to enable USB 2.0 on smdk5250. It includes addition of system and power management registers, functions to enable and disable power to the USB host controller.
This patchset is based on: USB: S5P: Add ehci support.patch
Rajeshwari Shinde (5): exynos5: Add system register structure exynos5: Add structure for PMU register exynos5: Add power Enable/Disable for USB-EHCI exynos5: usb: Fix incorrect USB base addresses exynos5: usb: Enable USB 2.0 on smdk5250

You can boot the system completely off a USB stick ...
