****************************** NOTICE *****************************
You have seen this notice as you have enabled OTG driver for mx53 LOCO board
For mx53 loco board, the OTG function is unavailable due to hardware limitation
So, Only one usb function (device or host) can be available for certain image
Please config your kernel to disable OTG and the usb function you don't want to use
And remain the other usb function you would like to use
Below OTG configs should be removed:
CONFIG_MXC_OTG, CONFIG_USB_OTG
Choose one of below configs for host or device function
But DO NOT choose them together
OTG host config
CONFIG_USB_EHCI_ARC_OTG
OTG device config
CONFIG_USB_GADGET
