[U-Boot] mpc83xx: USB: "Machine check in kernel mode" with usb start on mpc8315erdb

[Mahajan Vivek-B08308]

Hello there,
 
I built u-boot for mpc8315erdb from the current master @ http://git.denx.de/u-boot.git/ after enabling USB via adding the following #defines in include/configs/MPC8315ERDB.h:-
 
#define CONFIG_CMD_USB
#define CONFIG_USB_EHCI
#define CONFIG_USB_EHCI_FSL

But I ran into the following "machine check" after running usb start from the u-boot prompt. No USB device is plugged in. Please let me know if the above mentioned USB config options are sufficient to get the basic USB up and running.
 
Any help in this matter is highly appreciated.
 
Thanks,
Vivek
