IMHO, we should just have spl/board/<vendor>/<board>/ .

Let spl/board/<vendor>/<board>/Makefile decide what it wants to
build.

I mean something like this(similar changes for ONENAND):

+.PHONEY : SPL
+SPL	:$(TIMESTAMP_FILE) $(VERSION_FILE) depend tools
+	$(MAKE) -C spl/board/$(BOARDDIR) all
+
+ifeq ($(CONFIG_SPL),y)
+ALL += SPL
+endif
+
  __OBJS := $(subst $(obj),,$(OBJS))
  __LIBS := $(subst $(obj),,$(LIBS)) $(subst $(obj),,$(LIBBOARD))
