/*
 * USB device controllers have lots of quirks.  Use these macros in
 * gadget drivers or other code that needs to deal with them, and which
 * autoconfigures instead of using early binding to the hardware.
 *
 * This SHOULD eventually work like the ARM mach_is_*() stuff, driven by
 * some config file that gets updated as new hardware is supported.
 * (And avoiding all runtime comparisons in typical one-choice configs!)
 *
 * NOTE:  some of these controller drivers may not be available yet.
 * Some are available on 2.4 kernels; several are available, but not
 * yet pushed in the 2.6 mainline tree.
 *
 * Ported to U-Boot by: Thomas Smits <ts.smits@gmail.com> and
 *                      Remy Bohmer <linux@bohmer.net>
