The mkits.sh prepares a .its file describing a FIT image. This commit extends it to support a -s option, that allows to pass a file that should be embedded as a U-Boot script in the FIT image. This will be used as part of the dm-verity integration to add in the FIT image a U-Boot script that provides the details of the dm-verity volume (salt, root hash, number of data blocks, start of hash blocks, etc.).
