   1/*
   2 * USB device controllers have lots of quirks.  Use these macros in
   3 * gadget drivers or other code that needs to deal with them, and which
   4 * autoconfigures instead of using early binding to the hardware.
   5 *
   6 * This SHOULD eventually work like the ARM mach_is_*() stuff, driven by
   7 * some config file that gets updated as new hardware is supported.
   8 * (And avoiding all runtime comparisons in typical one-choice configs!)
   9 *
  10 * NOTE:  some of these controller drivers may not be available yet.
  11 * Some are available on 2.4 kernels; several are available, but not
  12 * yet pushed in the 2.6 mainline tree.
  13 *
  14 * Ported to U-Boot by: Thomas Smits <ts.smits@gmail.com> and
  15 *                      Remy Bohmer <linux@bohmer.net>
