I think we are still missing the case of some option being defined one
way in the SPL build case but another the regular case, which one should
be added to the defconfig?

In a set of slides[0] I found on the subject it looks like there was
going to be a system where we could conditionally define options in
defconfig based on whether we were building SPL or not. So we could run
moveconfig in multiple passes and find what kind of tag we need.

S:CONFIG_FOO=200
T:CONFIG_FOO=300
ST:CONFIG_BAR=y
+S:CONFIG_BAZ=y
+T:CONFIG_QUX=y
+ST:CONFIG_QUUX=y
etc..

Did this ever get implemented?
