+  CFE bootloader for BCM4908 uses custom image format. It consists of:
+  1. Optional cferom image
+  2. bootfs JFFS2 partition (cferam, kernel, DTB and optional helper files)
+  3. padding
+  4. rootfs simply appended to the bootfs + padding
+  5. tail with checksum and basic device info
+
+  This util allows creating, modifying and extracting from BCM4908 images.
