To: barebox
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.

The size and offset of the barebox partition in nand and spi nor flash
may vary on different boards. Make it possible to pass this information
over boardfile if needed.

pcm051 uses four MLO NAND partitions, so the default offset
to the barebox can not be used. Pass custom struct.
