I guess to really solve this, we need the following changes:
In the all kernels:
For both arch/*/boot and arch/*/boot/dts: clean removes *.dtb
In kernels that build *.dtb in the new location:
make dtbs and make foo.dtb both rm ../*.dtb
In kernels that build *.dtb in the old location:
make dtbs and make foo.dtb both rm dts/*.dtb
Is that too much to retrofit into all the stable kernels?
