Flattened Image Tree (FIT)

-The FIT format is alreay widely used in U-Boot. It is a flattened device
+The FIT format is already widely used in U-Boot. It is a flattened device
tree (FDT) in a particular format, with images contained within. FITs
include hashes to verify images, so it is relatively straightforward to
add signatures as well.
