[U-Boot] [PATCH] ls1046aqds: update the defaule mtdparts

[Xiaowei Bao]

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?
