As we also explained in thread: [RFC PATCH 0/2] USB: XHCI: Add xHCI
host controller stack	driver
http://comments.gmane.org/gmane.comp.boot-loaders.u-boot/145112
although code is based on linux's xHCI host controller driver,
at certain points putting some delays seemed to make the device
working.

The driver was certainly not fine tuned and needed further rework
which we couldn't
do due to other responsibilities. :-(
