  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>
