I notice that the dtb content in spl/u-boot-spl.bin and u-boot.bin not
able to update after I modify the dts file and make again, I have to
"make clean" first, and then the "make" can update the dtb content
to output binary, which lead to bad efficiency when try to modify dts.
I have try below command, the dtb file also not updated before "make clean".
dtc -I dtb -O dts spl/u-boot-spl.dtb
Is there any one can help fix this issue?
I have noticed this too, and also that changing a .dtsi file is not noticed.
Probably it is missing a dependency in the makefile.
I could not reproduce the issue for me.
Editing a DT file and re-compiling gave me the expected result.

If I am missing something, could you tell me the command you used for reproducing the problem?
