This ends up being the wrong approach as it then pulls in drivers/memory/stm32-fmc2-ebi.o on all of those platforms, in SPL, which is not what's intended. We need an SPL_MEMORY symbol and then gate the directory on that.
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?
Well, for consistency code should use IS_ENABLED(MEMORY) which will be true for CONFIG_MEMORY or CONFIG_SPL_MEMORY.
nit: CONFIG_IS_ENABLED(MEMORY)
Perhaps we can look at my Kconfig series so it can become CONFIG(MEMORY) and we can drop all the SPL_TPL_ stuff in Makefiles?
I think that was the part I had some reservations about, but we should re-visit that idea as I wasn't disagreeing (I believe) with making the logic easier, but I think that we need to re-evaluate how we manage the SPL/TPL/full U-Boot idea.
