++ * OHCI HCD(Host Controller Driver) for USB.

++ *
++ * Bus glue for Toshiba Mobile IO(TMIO) Controller's OHCI core
++ *(C) Copyright 2005 Chris Humbert <mahadri-usb@drigon.com>
++ *
++ * This is known to work with the following variants:
++ * TC6393XB revision 3 (32kB SRAM)
++ *
++ * The TMIO's OHCI core DMAs through a small internal buffer that
++ * is directly addressable by the CPU. dma_declare_coherent_memory
++ * and DMA bounce buffers allow the higher-level OHCI host driver to
++ * work. However, the dma API doesn't handle dma mapping failures
++ * well(dma_sg_map() is a prime example), so it is unusable.
++ *
++ * This HC pretends be a PIO-ish controller and uses the kernel's
++ * generic allocator for the entire SRAM. Using the USB core's
++ * usb_operations, we provide hcd_buffer_alloc/free. Using the OHCI's
++ * ohci_ops, we provide memory management for OHCI's TDs and EDs. We
++ * internally queue a URB's TDs until enough dma memory is available
++ * to enqueue them with the HC.
++ *
++ * Written from sparse documentation from Toshiba and Sharp's driver
++ * for the 2.4 kernel,
