5dd75e3b46 dm: usb: xhci: Use explicit parameters for xhci_setup_addressable_virt_dev()
This function should not be delving into struct usb_device. Pass in the
parameters it needs directly.

421a5a0c98 usb: 64-bit architectures support for xHCI
This commit allows xHCI to use both 64 and 32 bit memory
physical addresses depending on architecture it's being built for.
Also it makes use of readq()/writeq() on 64-bit systems

5853e1335c USB: xHCI: Add stack support for xHCI
This adds stack layer for eXtensible Host Controller Interface
which facilitates use of USB 3.0 in host mode.

Adapting xHCI host controller driver in linux-kernel
by Sarah Sharp to needs in u-boot.

Initial porting from Linux kernel version 3.4, with following
top commit history of drivers/usb/host/xhci* :
cf84055 xHCI: Cleanup isoc transfer ring when TD length mismatch found

This adds the basic xHCI host controller driver with bare minimum
features:
- Control/Bulk transfer support has been added with required
  infrastructure for necessary xHC data structures.
- Stream protocol hasn't been supported yet.
- No support for quirky devices has been added.
