   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>
