Hi,
I think you can get rid of quite a bit more of the repeated data for
most boards, see below.

Please allocate these in the common ehci platform init code
so you don't have to repeat the same nop_usb_xceiv for each
board-*.c file. If you need to override these, then you can
pass something instead of NULL to the init function.

This is OK as it's the board specific data needed. If it's the
same for many boards, then you might want to add some init function
for the default case.

It then seems that this can be in the common ehci platform init
code for most cases.

And this part too in most cases.
