This series is a follow-up series to previous series [1] that adds support for USB 3.0 hubs.
USB 3.0 hubs have slightly different hub descriptor format, as well as different port status bit positions. These needs to be properly handled by U-Boot USB core stack codes. xHCI driver has also been updated to correctly set up context structures that are required for devices behind a 3.0 hub to work.
Besides USB 3.0 hubs support, this series also adds support for low speed/full speed devices connected behind a high speed hub with the xHC controller. It turns out the 'Transaction Translator' part in the xHC data structure is missing.
Note there is one error during testing USB keyboard when CONFIG_USB_KEYBOARD is on.
"Failed to get keyboard state from device 413c:2105"
The enumeration process did pass and the error was thrown in the USB keyboard driver. This was due to the interrupt transfer is still not supported by xHCI driver, as of today.
This series is available at u-boot-x86/xhci-working2 for testing.

Applied to u-boot-usb/master, thanks.
