[U-Boot] [RFC PATCH 2/2] USB: xHCI: Add stack support for xHCI

[Marek Vasut]

Dear Vivek Gautam,

> This adds stack layer for eXtensible Host Controller Interface
> which facilitates use of USB 3.0 in host mode.

> This work is based on xHCI host controller driver in linux-kernel
> by Sarah Sharp.
> The code corresponding to xhci.c, xhci-mem.c, xhci-ring.c and
> xhci-hub.c in linux-kernel is grouped together here in
> single driver 'xhci.c'.

I wouldn't object keeping them separate so they can be easily synced with the 
Linux code actually. Can you try doing it that way ? (Pull it from Linux and do 
just minimal adjustments to wire it into U-Boot ... maybe implement some 
translation layer) ?
