Notes on the the generic USB-OHCI driver========================================This driver (drivers/usb/usb_ohci.[ch]) is the result of the merge ofvarious existing OHCI drivers that were basically identical besidecpu/board dependant initalization. This initalization has been movedinto cpu/board directories and are called via the hooks below.Configuration options----------------------	CONFIG_USB_OHCI_NEW: enable the new OHCI driver	CFG_USB_OHCI_BOARD_INIT: call the board dependant hooks:		  - extern int usb_board_init(void);		  - extern int usb_board_stop(void);		  - extern int usb_cpu_init_fail(void);	CFG_USB_OHCI_CPU_INIT: call the cpu dependant hooks:		  - extern int usb_cpu_init(void);		  - extern int usb_cpu_stop(void);		  - extern int usb_cpu_init_fail(void);	CFG_USB_OHCI_REGS_BASE: defines the base address of the OHCI				registers	CFG_USB_OHCI_SLOT_NAME: slot name	CFG_USB_OHCI_MAX_ROOT_PORTS: maximal number of ports of the				     root hub.Endianness issues------------------The USB bus operates in little endian, but unfortunately there areOHCI controllers that operate in big endian such as ppc4xx andmpc5xxx. For these the config option	CFG_OHCI_BE_CONTROLLERneeds to be defined.PCI Controllers----------------You'll need to define	CONFIG_PCI_OHCIIf you have several USB PCI controllers, define	CONFIG_PCI_OHCI_DEVNO: number of the OHCI device in PCI listIf undefined, the first instance found in PCI space will be used.PCI Controllers need to do byte swapping on register accesses, so theyshould to define:	CFG_OHCI_SWAP_REG_ACCESS
