Note that this is sometimes handled via config.mk fragments:
ifdef CONFIG_SPL_BUILD
ALL-y += $(OBJTREE)/MLO
else
ALL-y += $(obj)u-boot.img
endif
Or similar. I don't know what's better.
Ah. I was wondering if there were some magic that existing boards were
using, but couldn't find it.
I think I'd prefer having a simple CONFIG_SPL_TARGET, and boards that
need something more complicated can still provide a config.mk
fragment. What is the CONFIG_SPL_BUILD test for? Is ALL-y really
evaluated twice?
