Looking at the linux kernel the clock-frequency property of
the device tree is used to set the bus speed and not the
fclk_rate. Adapted this to be compliant with linux kernel.

A lot of boards use display-timings nodes to define the timings of one or more
displays. This command makes it possible to list and select displays which are
defined in a device tree.

This adds a buffer for log messages and a 'dmesg' command to
print the messages. The log buffer is implemented as log objects
rather than a string buffer. This makes it easy to implement
limiting the messages, cleaning the buffer and timestamping
the messages.

Additionally to the MLO update handlers also register the update
handlers for the regular barebox image.

To be able to not only update the MLO in NAND but also the
regular barebox image.
Since this is implemented with help of the corresponding xload
handler this also removes the 'xload' from the Kconfig options
and the filename.

This changes the MUSB support from the original Kernel state to
be usable with barebox. Tested on a custom board and the Beaglebone
Black. The host port on the Beaglebone works, the OTG port works
in device mode, but not yet in host mode.
Based on the initial MUSB port from Rolf Evers Fischer.

Since the MUSB driver will have it's own directory the Kconfig
entries won't be in drivers/usb/gadget/Kconfig. This is incompatible
with the current 'choice' approach for udc drivers. The udc drivers
do not implement the global usb_gadget_poll() anymore, so we can
drop the choice and allow multiple gadget drivers.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
Instead of letting each driver implement usb_gadget_poll directly
implement this function in the core which then calls into the
drivers.

The AM3xxx can boot images containing a Configuration Header
(generated with omap_signGP) or images with GP Header (simple
size/address information in front of raw image). Update the
SPI NOR barebox update handler to detect the GP Header images.
These have 0x65726162 ('bare') at the offset header[10]. Also
automatically swap the endianess for non swapped images so
that the regular non swapped images can also be flashed.

We assumed that there is a special image format for SPI. This is not
the case. The AM33xx can boot either images generated with omap_signGP
or raw images which only have the image size and load address in front
of the image. Whether these images are booted from SPI or another
boot medium doesn't matter. The only special thing about SPI is that
the image is in big endian format.
- renames mk-am3xxx-spi-image.c to mk-omap-image.c as the image format
is not only supported by AM3xxx but also by the OMAP SoCs
- removes the option to specify the SoC
- introduces -s to build a big endian image
- detects if an image already is an image generated with omap_signGP
So the behaviour is like this:
raw image -> mk-omap-image -> prepend size/address -> image for SD/MMC
raw image -> mk-omap-image -s -> prepend size/address, big endian swap -> image for SPI
CH image -> mk-omap-image -> nothing, input == output
CH image -> mk-omap-image -s -> big endian swap -> image for SPI

something useful the driver bails out.
