LS1043ARDB SDK 0.5 Image file contents unclear

Section 2.1.4 is not clear to me as to the output produced by the various builds.  Let me ask some specific questions:

 

First of all, I know that a complete, bootable media (exclusive of u-boot) must contain a Linux Kernel, rootfs and device tree blob (DTB).  What is unclear to me is whether or not these three components are present in all of the builds.  For example, does a build output file with the extension rootfs.ext2.gz such as fsl-image-x11-ls1043ardb ... contain all three components?  Does it have to be unzipped on the media before it can be used?  How about the same files with extension rootfs.ext2.gz.u-boot?  Does the u-boot extension mean the file also contains u-boot and can be copied to the boot area on the target media and then the complete image is ready to boot?  How about the itb files.  I understand that they all contain the three required components.  That sounds like a much better format to use, but I don't see how you generate an .itb file through configuration - how would I create an .itb file for the x11 build?

 

Thanks,

Don
