powerpc/usb:Differentiate USB controller base address

2013-10-24T16:35:09+00:00

Introduce different macros for storing addresses of multiple
USB controllers. This is required for successful initialization
and usage of multiple USB controllers inside u-boot

usb: udc: add udc.h include file

2013-10-20T21:46:38+00:00

Move common definitions to udc.h
This allows musb_udc.h to be removed as well.

usb: gadget: mv_udc: split mv_udc.h file

2013-10-20T21:46:36+00:00

Move defines only needed by mv_udc.c to a file
in the same directory.

This allows usbtty to compile for mv_udc,
but it still doesn't link.

usb: mv_udc: Add bounce buffer

2013-07-29T21:01:33+00:00

The requests sent to the controller are not properly cache aligned
most of the time, thus implement a simple bounce buffer to avoid
problem with cache.

usb: mv_udc: Improve allocation of qTD items

2013-07-29T21:01:32+00:00

Allocate the qTD items all at once instead of allocating them
separately. Moreover, make sure each qTD is properly aligned
to 32-bytes boundary and that cache can be safely flushed over
each qTD touple.

usb: mv_udc: Move QH and qTD into mv_drv

2013-07-29T21:01:32+00:00

Both the endpoint queue head and the endpoint item list is a controller
specific thing. Move them both into controller private data.

usb: mv_udc: Make use of struct ehci_ctrl

2013-07-29T21:01:31+00:00

The usb_lowlevel_init() call already fills and passes back struct
ehci_ctrl , which readily contains correctly determined address of
the port register block address computed from values from controller
configuration registers. Leverage this and make use of this value
as this makes the code mode universal, but also gets us rid of the
CONFIG_USB_REG_BASE configuration option.

Moreover, this patch cleans up the usb_gadget_register_driver() call
a little by correcting the error handling. Note the usb_lowlevel_init()
and mvudc_probe() are now called in reversed order, but this has no
impact on the code.

usb: mv_udc: Clean up the EP initialization

2013-07-29T21:01:31+00:00

Move the constant values that are programmed into mv_ep.ep into
separate static const structure so they can be memcpy()'d when
the initialization happens.

Moveover, we only every init NUM_ENDPOINTS, not 2 * NUM_ENDPOINTS,
so fix this bug as well.

usb: mv_udc: Move endpoint array into driver data

2013-07-29T21:01:31+00:00

The endpoints are operated on a per-controller basis, move the
endpoint array into controller's private data. Also shuffle the
struct mv_ep structure definition just above the definition of
the struct mv_drv so they're well grouped together.

usb: mv_udc: Clean up mv_udc.h

2013-07-29T21:01:31+00:00

Do a coding-style cleanup of this file and throw away useless
defined values. These values were likely a result of a copy-paste
job.
