 ==============

+U-Boot is capable of booting (and performing other auxiliary operations on)
+images in two formats:
+
+New uImage format (FIT)
+-----------------------
+
+Flexible and powerful format based on Flattened Image Tree -- FIT (similar
+to Flattened Device Tree). It allows the use of images with multiple
+components (several kernels, ramdisks, etc.), with contents protected by
+SHA1, MD5 or CRC32. More details are found in the doc/uImage.FIT directory.

+
+Old uImage format

+Old image format is based on binary files which can be basically anything,
