Yeah, that's some non-obvious U-Boot build magic:
Whenever there is a file which has "-u-boot.dtsi" appended to
certain .dts filename stubs, U-Boot includes this file when building
the .dtb. This is supposed to be used to add U-Boot specific DT nodes
or properties to some otherwise unchanged (read: Linux mainline) DTs.
Check scripts/Makefile.lib and search for u-boot.dtsi for the source.
Cheers,
Andre.
