A weak version of the function board_usb_init is implemented in: common/usb.c drivers/usb/host/xhci-omap.c
To fix the double implementations:
- Convert the board_usb_init function in drivers/usb/host/xhci-omap.c normal (not weak).
- The function board_usb_init in drivers/usb/host/xhci-omap.c calls to the weak function omap_xhci_board_usb_init.
- Rename board version of the function board_usb_init to omap_xhci_board_usb_init. Done only for boards that defines CONFIG_USB_XHCI_OMAP.
To achieve the same flexibility with the function board_usb_cleanup:
- Add a normal (not weak) implementation of the function board_usb_cleanup in drivers/usb/host/xhci-omap.c
- The function board_usb_cleanup in drivers/usb/host/xhci-omap.c calls to the weak function omap_xhci_board_usb_cleanup.
- Rename board version of the function board_usb_cleanup to omap_xhci_board_usb_cleanup. Done only for boards that defines CONFIG_USB_XHCI_OMAP.
