I don't understand, how can a single U-Boot(proper) support multiple
Rockchip SoCs,
it sounds awesome which is kernel like. But I thought we need different
build
with different source for different SoCs now.

For $(SOC)-u-boot.dtsi, another way is using $(BOARD)-u-boot.dtsi, but I
think in
most case, we can have one $(SOC)-u-boot.dtsi instead of many
$(BOARD)-u-boot.dtsi
for one SoC, so we need this feature.

Thinks,
