If you do a sandbox build you will see this file: arch/sandbox/dts/.sandbox.dtb.cmd It contains the dependencies used to compile the device tree. Can we use the same mechanism? There is a .cmd file for the dsdt file but it does not seem to have the correct contents. Regards, Simon

[PATCH v1 1/1] Makefile.lib: Always rebuild DSDT
The dsdt.asl is usually combined out of several files that are included in the main one. Whenever we change the content of any of such files, build system is not able to recognize them. Hence the easiest way is to force DSDT rebuild each time we run make.
