You mean SPL here ?

Is this needed at all ?

Looks like this is duplicated from socfpga_common.h , no ? Why don't you just
include socfpga_common.h ?

Please don't invent new ad-hoc config options which will permeate the U-Boot
build. Just put these as a variable into the extra environment if needed.

Why do you disable env import ?

Again, this is just a copy-paste from socfpga_common.h, no?
