This may cause a build failure with FIT_SIGNATURE disabled. I will have 
this fixed in v2. The correction is trivial.

Correct diff below for reference:

  FIT_OBJS-$(CONFIG_FIT) := fit_common.o fit_image.o image-host.o 
common/image-fit.o
-FIT_SIG_OBJS-$(CONFIG_FIT_SIGNATURE) := common/image-sig.o 
common/image-fit-sig.o
+FIT_SIG_OBJS-$(CONFIG_FIT_SIGNATURE) := image-sig-host.o 
common/image-fit-sig.o
