I have explained the details about this concern on v2 [1], thought you
would comeback on the same line instead here.

Anyway, making SPL as an optional is not an idea to go with Mainline
as we make many decisions with regards to make SPL is mandatory.
Since the DDR is show stopper here (and it would really need a good
amount of time, since it effect the other boards), I can go with TPL
enabled boot-chain where ddr bin, SPL and U-Boot proper can be part of
booting stages. This way we can avoid skipping SPL usage, and many
config changes to make SPL optional.
