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>
