+ * 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
