PS1: 
The DEP_FILES in the dependency list is empty, even though it can be printed out in the following command.

$(obj)/amdfw.rom:	$(call strip_quotes, $(PSP_BIOSBIN_FILE)) \
    		$(PSP_VERSTAGE_FILE) \
    		$(PSP_VERSTAGE_SIG_FILE) \
    		$$(PSP_APCB_FILES) \
    		$(DEP_FILES) \  <--- empty
    		$(AMDFWTOOL) \
    		$(obj)/fmap_config.h \
    		$(objcbfs)/bootblock.elf # this target also creates the .map file
    $(if $(PSP_APCB_FILES), ,$(error APCB_SOURCES is not set))
    rm -f $@
    echo DEP_FILEs $(DEP_FILES) <--- not empty

It seems that the Makefile.inc in soc/amd/common is prcessed after the soc/amd/cezanne/Makefile.inc
