[U-Boot] [PATCH RFC v2 0/6] usb: host: Add driver model support

[Vivek Gautam]

Hi Marek, Simon,

This patch-series comes as a update for an earlier posted series[1]
"[PATCH RFC 0/2] usb: host: Add a wrapper layer for mutiple host support"
which was posted long back.

We had discussion to introduce the driver model instead of the approach used
in [1]. The driver model seems pretty straight-forward and easier to implement
 besides giving a clean approach to use multiple host controller types, viz.
EHCI, XHCI or OHCI simultaneously on a platform which has such provision.

It's rather bad on my side that it took so long to post the updated version.
Got busy with the projects. :-(

So here's the RFC-v2 which implements the driver model approach.
I have added support on OHCI, EHCI and XHCI and enabled EHCI and XHCI
 on Exynos5250 machines. Though not tested thoroughly, i can see EHCI
and XHCI working together (enumerating the Root hubs).

Let me know you comments on what you think of current approach.

Thanks
Vivek
