A lot of stuff is removed by the top level Makefile [1]. But as the 
patch "arm/dt: Add dtb make rule" adds the .dtb generation to 
arch/arm/boot/Makefile, we thought it would be a good place to add the 
removal of that file there, too.

Hmm, not sure if this answers your question, though ;)

Best regards
