Sorry for the late response.

I have to admit that I really dislike the big "#ifndef CONFIG_MPC512X"
in drivers/usb/host/ehci-fsl.c - it covers basicly all of the existing
code, and adds an alternative implementation for MPC512x.  I think
this should better be handled in a separate driver.

Patch following.

Best regards,

Wolfgang Denk
