This variable is not used and causes a warning. Please remove it.
After applying this patch things go further when I boot with a USB
thumb connected to the USB Host1 port:
ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
usbcore: registered new interface driver usb-storage
53ff4400.usb supply vbus not found, using dummy regulator

(Not sure why it says full-speed device. When I connect the same
device to a PC it says high-speed)
usb 1-1: not running at top speed; connect to a high speed hub

imx-sdma 53fd4000.sdma: firmware not found
(Then system hangs here).
If I boot without the USB thumb connected, then I reach the prompt,
however after inserting the USB pen drive into USBH1 there is no
detection.
Any ideas?
Thanks,
Fabio Estevam
