-+ *(C) Copyright 2000-2002 David Brownell <dbrownell@users.sourceforge.net>

-+ *
-+ * 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,
