From: Yegor Yefremov <yegorslists@xxxxxxxxxxxxxx>
In U-Boot configuration name is passed as a string after
address in bootm command after '#' separator. In Barebox
a string coming after '@' separator will be converted to
integer.
This patch adds additional field os_conf to the image_data
structure in order to save the string after '@' as is and pass
it to fit_open() routine.
