Then you will have to deal with many such images in the top-level
Makefile(u-boot/Makefile). Instead why not have just one rule like the
below in the top-level Makefile for all the different spl's:
SPL :$(TIMESTAMP_FILE) $(VERSION_FILE) depend tools
$(MAKE) -C spl/board/$(BOARDDIR) all
And leave the rest to the board level Makefiles
Of course, this is assuming the existing Makefile structure. With the
new Makefile structure you are suggesting this may not hold good.
