Notes on the the generic USB-OHCI driver
========================================
-This driver (drivers/usb_ohci.[ch]) is the result of the merge of
+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.
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
+ CONFIG_SYS_USB_OHCI_REGS_BASE: defines the base address of the OHCI
registers
- CFG_USB_OHCI_SLOT_NAME: slot name
+ CONFIG_SYS_USB_OHCI_SLOT_NAME: slot name
- CFG_USB_OHCI_MAX_ROOT_PORTS: maximal number of ports of the
+ CONFIG_SYS_USB_OHCI_MAX_ROOT_PORTS: maximal number of ports of the
root hub.
------------------
The USB bus operates in little endian, but unfortunately there are
-OHCI controllers that operate in big endian such as ppc4xx and
-mpc5xxx. For these the config option
+OHCI controllers that operate in big endian such as ppc4xx. For these the
+config option
- CFG_OHCI_BE_CONTROLLER
+ CONFIG_SYS_OHCI_BE_CONTROLLER
needs to be defined.

-PCI Controllers
-----------------
-
-You'll need to define
-
- CONFIG_PCI_OHCI
-
-PCI Controllers need to do byte swapping on register accesses, so they
-should to define:
-
- CFG_OHCI_SWAP_REG_ACCESS
