Hi Damien
this patch seems to be doing alot better then the original one.
The root hub is detected and also it detects a device connected to the controller.
However, by testing with a usbstick (mass storage) it fails to detect the device as a storage device.
I have here a debug printout which is being printed (with debug enabled) during execution of the command 'usb start':

If I type 'usb storage' it says it has one device but the type is unknown.
Hope you can assist me in this.

Subject: [U-Boot] [PATCH] Add support for the MPC5121e USB Host controller.
Add support for the USB Host controller of the MPC5121e, based on the original patch by Francesco Rendine [1].
The patch configures the USB Host controller and the on-board UTMI phy, including the Freescale-specific registers as per the Linux kernel driver.
Tested on the MPC5121ADS platform with various USB mass storage devices.
