Interesting.
A little comments.
- Is there any possibility that some files should be compiled for SPL only?
(I do not think we have much.)
Perhaps, obj-y : for U-boot only
obj-s : for SPL only
oby-ys: for both
I am not sure..
- This idea is only applicable for bool options.
We still have to keep duplication for int/hex options such as
CONFIG_SPL_TEXT_BASE.
But, this idea will help clean up much because most of configs are boolean.
