    firmware-utils: bcm4908img: convert into a package
    
    bcm4908img is a tool managing BCM4908 platform images. It's used for
    creating them as well as checking, modifying and extracting data from.
    
    It's required by both: host (for building firmware images) and target
    (for sysupgrade purposes). Make it a host/target package.

+define Package/bcm4908img/description
+  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.
