- Notes on the the generic USB-OHCI driver
- ========================================
- This driver (drivers/usb/usb_ohci.[ch]) is the result of the merge of
- various existing OHCI drivers that were basically identical beside
- cpu/board dependant initalization. This initalization has been moved
- into cpu/board directories and are called via the hooks below.
- Configuration options
- ----------------------
- CONFIG_USB_OHCI_NEW: enable the new OHCI driver
- CFG_SYS_USB_OHCI_REGS_BASE: defines the base address of the OHCI
- registers
- CONFIG_SYS_USB_OHCI_SLOT_NAME: slot name
- Endianness issues
- ------------------
- The USB bus operates in little endian, but unfortunately there are
- OHCI controllers that operate in big endian such as ppc4xx. For these the
- config option
- CONFIG_SYS_OHCI_BE_CONTROLLER
- needs to be defined.
