Eli Billauer a53d1202ae char: xillybus: Add driver for XillyUSB (Xillybus variant for USB)
The XillyUSB driver is the USB variant for the Xillybus FPGA IP core.
Even though it presents a nearly identical API on the FPGA and host,
it's almost a complete rewrite of the driver: The framework for exchanging
data on a USB bus is fundamentally different from doing the same with a
PCIe interface, which leaves very little in common between the existing
driver and the new one for XillyUSB.

Xillybus is a generic interface for peripherals designed on
programmable logic (FPGA). The driver probes the hardware for
its capabilities, and creates device files accordingly.
If unsure, say N.

Set to M if you want Xillybus to use PCI Express for communicating
with the FPGA. The module will be called xillybus_pcie.

Set to M if you want Xillybus to find its resources from the
Open Firmware Flattened Device Tree. If the target is an embedded
system, say M. The module will be called xillybus_of.
