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.
