From
Subject[PATCH] : Allow embedded developers USB options normally reserved for OTG
Date
From: Robin Getz <rgetz@blackfin.uclinux.org>

Allow embedded developers to turn support for USB Hubs off even if they have a
full root hub. This saves the overhead (RAM and Flash size).

Allow embedded developers the capabilities of the "otg_whitelist.h" - a
product whitelist, so USB peripherals not listed there will be rejected
during enumeration. This is the desired operation for many embedded products.
