i2c: omap: fix dts property "clock-frequency" usage ...

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.

Introduce message logging support ...

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.

ARM: am335x: Add a NAND update handler for the regular barebox ...

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.

clock: make get_time_ns() safe to be called without clocksource ...

make it possible to call get_time_ns() before the clocksource
has been registered. Just return 0 in this case which is still
better than crashing the system.

clock: Add a variable with the first timestamp after startup ...

For measuring the startup time it's useful to save the first

ARM: AM33xx SPI MLO update handler: detect non CH images ...

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.

scripts: mk-am3xxx-spi-image: fix wrong assumptions about SPI images ...

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
