The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini <trini@konsulko.com> Reviewed-by: Simon Glass <sjg@chromium.org>

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.
