mx5: USB host support for mx51evk and mx53loco

This patches series provides USB host support for the mx51evk and mx53loco. The generic ehci-mx5 interface is derived from ehci-mxc and uses the header files of the ehci-fsl interface. The callback board_ehci_hcd_init() allows to do board-specific setup when USB is started.

Hi,

isn't Jana already doing this kind of USB support for mx5 based on my old patches? You didn't notice?

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.

Wolfgang.
