I have a question about how CONFIG_SPL_MEMORY works together with CONFIG_MEMORY.

Do we use CONFIG_SPL_MEMORY only to gate the drivers/memory directory inclusion?
Then continue to use CONFIG_MEMORY and others to enable/disable driver
build for both non-SPL and SPL case?

So drivers/memory/Makefile remains as it is?
