+Subject: powerpc/fsl: Fix build of the dtb embedded kernel images
+
+Commit dc37374b9c833 ("powerpc/fsl: Move Freescale device tree files
+into fsl folder") moved a lot of device tree files into fsl directory,
+fixing Makefile for cuImage target only.  Unfortunately there are other
+targets which require embedding a device tree into the kernel image
+(e.g. dtbImage.%).  So use a more generic approach.
