[U-Boot] UMS on mx6sl

[Fabio Estevam]

Hi,

I am trying to get USB Mass Storage to work on mx6slevk, but I am
getting the following error:

=> ums 0 mmc 1
UMS: disk start sector: 0x0, count: 0x762c00
g_dnl_register: failed!, error: -22
ERROR: g_dnl_register failed
at common/cmd_usb_mass_storage.c:107/do_usb_mass_storage()

On mx6qsabresd it works fine and I am able to mount the SD/eMMC card
on the host PC.

The mx6slevk changes are the same as the ones for sabresd and look like this:

diff --git a/include/configs/mx6slevk.h b/include/configs/mx6slevk.h

Does anyone have any ideas of what may be missing?
