The OMAP3 supports uploading the first stage bootloader via USB.
The ROM leaves the MUSB controller enabled and it can then be used
to upload a 2nd stage image. This patch adds the omap3-usb-loader tool
and the necessary barebox support to upload the 2nd stage image.

The omap usb loader tool is downloaded from https://github.com/grant-h/omap_loader
and changed to also accept CHSETTINGS images.

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 adds a function which reads back the SDRAM controller settings.
This is used in a AM33xx specific barebox entry function and a
SDRAM driver which registers a SDRAM memory bank.

Storing the boot information in the image itself and passing a pointer
around between images is cumbersome and doesn't fit well with multiimage
support where the pointer we pass around is already occupied by the
devicetree.
Do the same as U-Boot does and store the boot information at the bottom
of the SRAM public stack.
To maintain the compatibility between new xloaders and older barebox
binaries we still pass the boot information to the next stage via pointer.

The ROM loader passes the address of a buffer to the MLO in
register 0. Store this data so we can find the boot source later.
On the same way the bootinformation are passed to the barebox,
then. It has to be enshured that r0 contains always the
buffer or the boot source detection will not work.

Applied this on all OMAPs. This patch is based on work of
Jan Luebbe <jlu@pengutronix.de>.

Compile tested on all OMAP boards.
Tested on pcm049, phyCARD-A-L1 and pcm051.

Currently, there are multiple definitions of run_shell()
for each board that can be build in "xload" configuration.
Now there is only one function used by all boards.

The functions defined in xload.c are used only when "xload"
configuration used; but it gets compiled unconditionally.
This has been fixed as well.
