FIT (Flat Image Tree) is the main image format used by U-Boot. In some cases scripts are used to create FITs within the U-Boot build system. This is not ideal for various reasons: - Each architecture has its own slightly different script - There are no tests - Some are written in shell, some in Python To help address this, add support for FIT generation to binman. This works by putting the FIT source directly in the binman definition, with the ability to adjust parameters, etc. The contents of each FIT image come from sub-entries of the image, as is normal with binman.
