Hi York,

This patch is for the ls1046aqds platform, In order to facilitate the test 
staff and customers to view the detailed partition information, so didn't 
define a larger partition to include all images, and the partition rule  is 
discussed internally as the default partitioning standard for the layerscape 
platform.

thanks

Do we really need to expose every image as individual partition? It is only 
useful if we need to access them under Linux. What's the chance to update 
U-Boot environmental variables under Linux? If you really to do so, you can 
probably be fine by defining a larger partition to include all images used for 
U-Boot. Agree?
