Since this is a non-default u-boot-nanopi-r4s-rk3399, perhaps instead
define a separate variant by making a custom configuration and applying
the patch only in that variant (e.g. u-boot-nanopi-r4s-rk3399-ddr3)?

Weather this is in addition to u-boot-nanopi-r4s-rk3399, or instead of,
is a bit of an open question. Would anyone use the default variant? how
common is that hardware?

live well,
