android - AOSP build display all PRODUCT_PACKAGES variable in .mk file

Question

I'm trying to build an AOSP rom. How can I display all variables in PRODUCT_PACKAGES in my target .mk file? Here is my code so far:

define dump-product-package
$(warning ==== $(1) ====)
$(warning $($(1).$(PRODUCT_PACKAGES))))
endef

$(warning **** dump product packages ****)
$(foreach p,$(PRODUCT_PACKAGES),$(call dump-product-package,$(p)))

The result is:

device/google/taimen/aosp_taimen.mk:58: warning: **** dump product packages ****
device/google/taimen/aosp_taimen.mk:59: warning: ==== @inherit:build/target/product/core_64_bit.mk ====

how do I display the PRODUCT_PACKAGES values from the inherited file? I know I need a recursive loop in the dump-product-package, I don't know what data type is for parameter $(1) or how to access it. Thanks.
