[U-Boot] [U-Boot-Users] Multiple USB controller support under Uboot

[Matthias Fuchs <matthias.fuchs@esd-electronics.com>]

Hi Mike,

U-Boot currently only supports one USB host controller at a time. So it's
wrong to say that U-Boot finds only one, but correct is, that U-Boot only
uses one.
Commands to switch between different controllers or multi controller support
is missing. 

You could add this feature ;-)
