Only one empty line is needed here.

This is wrong: you shouldn't tell users to look into output/build/. All
useful output should be in output/images/.

Also, these instructions are not very interesting: you should explain
how to actually "install" the kernel image and Device Tree blob.

Please look at other readme.txt in Buildroot to see good examples. I
think board/raspberrypi2/readme.txt is a good example.

Thanks,

Thomas
