Well, I already responded on Jana's patches and presented my ideas here:

  http://marc.info/?l=u-boot&m=132067806107887&w=2

Unfortunately, only the mails with subject "[PATCH] ..." get enough
attention ;-).

The big difference to Jana's patch is that he uses a board-specific
implementation (ehci_hcd_init() is in board specific code). I think we
should share some code.
