This feature was added by Nathan likely for yocto purpose.

     microblaze: Build only DTBs for selected target

     Adding more targets to repository requires some additional
     changes not simply just adding config file, defconfig and dts.
     This patch makes this process easier by building only
     particular DTB which is selected via defconfig
     that Makefile doesn't need to contain all dts files in the repository.

Mark: Can you please double check what Yocto is doing for supporting multiple 
microblaze based DTs? If you are copying dtses to u-boot source code and then 
using CONFIG_DEFAULT_DEVICE_TREE to select DT to build?

Thanks,
Michal
