How to build linux kernel img and dtb for S905D3

I just want to build kernel img and dtb for S905D3。 It takes too long to compile the entire project use commond PROJECT=Amlogic-ng ARCH=arm make image.

I just modify kernel and dts . Is there a way to compile the version more quickly?

scripts/build linux

But it will precompile all dependencies so it will also take long time. And you will have to grab the files from the build dir.
